The rear seat 10 is a chair in which a seat back 16 is attached to a seat cushion 12 so that the seat back 16 can be angularly adjusted through reclining mechanisms14, and a head rest 18 is inserted into the seat back 16 from above. The rear seat 10 is attached to a floor 21 through metal fittings 22 so as to be turnable clockwise, in the drawing, around a pin 23 of the metal seat fittings 22.
The seat cushion 12 is normally locked to the floor 21 by means of seat lock mechanisms 65. The details of the seat lock mechanisms 65 will be described later.
FIG. 3 is a view taken in the direction of the arrow B in FIG. 2, showing the rear seat viewed from the tail gate side (in the drawing, three head rests 18 are illustrated but no metal seat fittings are illustrated).
As seen in the drawing, a pull fitting 25, a first unlocking lever 45, and a second unlocking lever 60 are provided in the back 17 of the seat back 16 according to the present invention. The first unlocking lever 45 serves a seat back unlockinglever, and the second unlocking lever 60 serves a seat cushion unlocking lever.
FIG. 4 is a sectional view taken along line I--I in FIG. 3, showing the attachment structure of the pull fitting 25.
Basically, the seat back 16 is configured as follows. That is, a plurality of vertical frames 28 are made to bridge across pipes 27 and 27, and wires (not shown) are put between these vertical frames 28 in the form of lattice to thereby form askeleton frame 30. A cushion material (not shown) is attached to the skeleton frame 30. The skeleton frame 30 with the cushion material is covered with a skin 32. The structure of the place to which the pull fitting 25 etc. is as follows.
A first bracket 33 is fixed to the skeleton frame 30, and an angle-like second bracket 34 which is attached to the base of the pull fitting 25 is attached to the first bracket 33 by means of a bolt 35.
In addition, the skin 32 is provided with an opening 36, and a receiving member 37 and a garnish 38 are placed against the opening 36 from the back and the front respectively, so that the skin 32 is held by the receiving member 37 and the garnish38. The base of the pull fitting 25 is made to face the garnish 38 and the receiving member 37 so that a top end 39 of the receiving member 37 is made to abut against the second bracket 34.
The garnish 38 is a kind of decorated lid molded with resin, and designed so that it can be freely attached to and detached from the receiving member 37 by fitting a fall pin 38a into the receiving member 37.
The opening 36 of the skin 32 is required to be reinforced. Accordingly, the opening 36 portion is pressed by the garnish 38 against the receiving member 37. In addition, since the top end 39 of the receiving member 37 is made to abut againstthe second bracket 34, there is no fear that the garnish 38 and the receiving 37 rattle back and forth (right and left in the drawing).
The pull fitting 25 is a strap constituted by a belt 25a and a pull ring 25b, and a lock member 40 is attached near the pull ring 25b. The lock member 40 is constituted by a receiving piece 41 which is attached to the seat back 16 and a movingpiece 42 which is attached to the belt 25a. The receiving member 41 can be coupled with the moving piece 42. A pair of surface fasteners, a pair of permanent magnet and ion strip, a pair of hooks, or the like, may be used as the lock member so that oneand the other of the pair are used as the receiving piece 41 and the moving piece 42 respectively.
By the locking function of the lock member 40, the pull fitting 25 can be locked to the back 17 of the seat back 16.
FIG. 5 is a sectional view taken along line II--II in FIG. 3, showing the attachment structure of the first unlocking lever 45.
The plurality of vertical frames 28 are made to bridge across the pipes 27 and 27, wires 29 and 29 are put between these vertical frames 28 in the from of lattice to thereby form the skeleton frame 30. A third bracket 46 which supports the firstunlocking lever 45 swingably is fixed to the skeleton frame 30. A receiving member 48 with an opening 47 is extended from the third bracket 46 to the vicinity of the skin 32 so that the opening 47 is made coincident with an opening 49 of the skin 32. Agarnish 51 is inserted into the opening 47 of the receiving member 48 so as to press the opening 49 of the skin 32. Thus, the skin 32 is held between a flange 52 and the receiving member 48.
If the first unlocking lever 45 is turned clockwise around a pin 53 to a position shown by an imaginary line, an unlocking wire 54 can be pulled up. This makes it possible to unlock the reclining mechanisms 14 shown in FIG. 2.
When the first unlocking lever 45 is opened as shown by the imaginary line, the inside of the seat cushion is exposed. A decorative plate 55 is therefore provided to prevent the exposure of the inside of the seat cushion.
FIGS. 6A and 6B are sectional views taken along line III--III in FIG. 3, showing the attachment structure of the second unlocking lever 60.
FIG. 6A shows that a concave portion 58 is provided in the rear 57 of the seat cushion 12 and the second unlocking lever 60 has been received in the concave portion 58.
In FIG. 6B, if a second unlocking lever 60 is manually turned around a pin 61, an unlocking wire 62 can be pulled up. The seat unlocking mechanism 65 to be unlocked on this occasion will be described below in detail.
FIGS. 7A and 7B are detailed drawings of a portion 7 shown in FIG. 2 for explaining the seat lock mechanism.
Referring to FIG. 7A, the seat lock mechanism 65 is constituted by a U-shaped metal fitting 66 attached to the floor, a bracket 67 attached to the seat cushion, a U-shaped groove 68 formed in the bracket 67, a lock claw 71 which can be turnedaround a pin 69 so as to enter and leave the U-shaped groove 68, a spring 72 which urges the lock claw 71 in the unlocking direction (clockwise), a retaining claw 73 which keeps the lock claw 71 in the locking position, and the unlocking wire 62 whichmakes the retaining claw 73 turn around a pin 74.
FIG. 7A shows the seat locked state in which the U-shaped metal fitting 66 has entered the U-shaped groove 68 so as to be positioned by the lock claw 71. Before the rear seat is received, that is, normally, the rear seat is in this state so thatthere is no fear that the rear seat rattles.
When the unlocking wire 62 is pulled for unlocking purposes, the retaining claw 73 begins to rotate clockwise. When the retaining claw 73 has rotated to some extent, the portion where the retaining claw 73 comes into contact with the lock claw71 moves from a convex portion 75 to a concave portion 76. The lock claw 71 cannot be locked in the concave portion 76, that is, the lock claw 71 slides in the concave portion 76 and the lock claw 71 is rotated clockwise by the pulling function of thespring 72.
FIG. 7B shows the unlocked state. This means that the seat cushion has become separated from the floor.
The function of the thus configured seat receiving structure is described with reference to FIGS. 8 and 9. The following operations are performed from the outside of the car under the condition that the tail gate is opened.
FIGS. 8A and 8B are explanatory drawings for the function of the rear seat according to the present invention (first half).
Referring to FIG. 8A, the first unlocking lever 45 is fallen down as shown by the arrow C. This operation makes the reclining mechanism 14 unlock. The seat back 16 is then fallen down forward as shown by the arrow D and placed on the seatcushion 12. Then, if the hand is put off from the first unlocking lever 45, the reclining mechanism 14 is returned to the locked state. Thereafter, it becomes possible to handle the seat cushion 12 and the seat back 16 integrally with each other.
In FIG. 8B, the pull ring 25b is separated from the seat back 16 as shown by the arrow E to facilitate pulling of the pull ring 25b. The second unlocking lever 60 is then fallen down as shown by the arrow F while the pull ring 25b is pulled tothe outside of the car so that the seat lock mechanism 65 is unlocked. Now, the whole of the rear seat 10 is rotated as shown by the arrow G.
FIGS. 9A and 9B are drawings for explaining the function of the rear seat according to the present invention (second half).
In FIG. 9A, the rear seat 10 is further rotated as shown by the arrow H so as to be received in the receiving concave portion 11. The rear seat 10 is received so that the bottom 12a of the seat cushion 12 becomes substantially even with thefloor 21. Thus, the storage of the rear seat 10 in the floor 21 is completed.
On the other hand, in FIG. 9B, to return the rear seat 10 to the original position, one may put his/her hand on a pull handle 78 formed on the bottom 12a of the seat cushion 12 and lift the pull handle 78 to an extent as shown by the arrow I.Then, the rear seat 10 can be turned forward as a whole. Thereafter, if one returns the seat cushion 12 to its substantially horizontal position and erect the seat back 14, the rear seat 10 is returned to its initial posture.
In addition, the first unlocking lever and the seat cushion unlocking lever may be designed so as to be operated from the tail gate side or operated within the room.
The present invention fulfills the following effects by the aforementioned configuration.
An operator opens the tail gate, and stretches his/her arm through the tail gate to make the seat back fall down forward. Then, the operator pulls the pull fitting to make both the seat back and the seat cushion turn over backward so as to bereceived in the storage concave portion. Accordingly, this design allows an operator to perform the rear seat rearrangement in a very easy posture from the outside of a car.
The pull fitting is fastened to the back of the seat back. This makes it possible to prevent the swinging of the pull fitting, etc.
Since the skin is held between the receiving member and the garnish, the opening of the skin can be prevented from being deformed. In addition, since the receiving member is made to abut against the second bracket, the receiving member preventedfrom displacing laterally and the receiving member and the garnish are prevented from rattling.
Further, since the first unlocking lever is provided in the back of the seat back, the reclining mechanism can be unlocked from the tail gate side. Therefore, by the operations of the first unlocking lever together with the pull fitting, therear seat rearrangement can be performed easily from the outside of the car.
Further, since the skin is held between the receiving member and the garnish, the opening of the skin can be prevented from being deformed. In addition, since the third bracket supporting the first unlocking lever is fixed to the skeleton frame,a large force can be applied to the first unlocking lever.
Still further, since the second unlocking lever is provided in a rear portion of the seat cushion, the seat locking mechanism can be unlocked from the tail gate side. Therefore, by the operations of the first unlocking lever together with thepull fitting, the rear seat rearrangement can be performed easily from the outside of the car.
Although the invention has been described in its preferred formed with a certain degree of particularity, it is understood that the present disclosure of the preferred form can be changed in the details of construction and in the combination andarrangement of parts without departing from the spirit and the scope of the invention as hereinafter claimed.
