Description

[Detailed description of the invention] This invention relates to a support structure for a rear seat device for an automobile, and more specifically, a support structure for holding the seat cushion and seat back of the rear seat in an upright position when the seats are folded and stored. Regarding structure.

Conventionally, this type of configuration was used, for example, in the 1970s.
There is one shown in Publication No. 21234. In this configuration, the seat cushion and seat bag of the rear seat are folded and placed in an upright position so that they can be stored on the back of the front seat. In order to maintain the stowed position of the seat, one end of the band is secured to the rear of the seat cushion via a pivot rod, and the other end of the band is attached to a hanging ring provided on the back of the front seat. It is removably locked to.

By the way, in the above configuration, in order to lock the band, a hanging ring is provided on the front seat and a pivot rod is provided on the rear seat, which complicates the seat configuration and increases costs. Cause. Further, it is not desirable in terms of appearance to provide such a pivot rod on the seat.

This idea was developed with the above-mentioned circumstances in mind, and by effectively utilizing the parts of the seat to hold the folded seat in an upright position when the seat is stowed, it is possible to The purpose is to simplify the configuration for holding the seat in an upright position and to improve the appearance of the seat.

The features of this invention to achieve the above purpose are that it locks the tilted posture of the seat back;
Alternatively, in a rear seat device having a lock operation lever that can be released, a locking member is provided on the fixed side of the vehicle body, and the locking member locks the lock operation lever so as to maintain the upright posture of the folded seat. The point is that it is removably locked.

Examples of this invention will be described below with reference to the drawings.

A commercial vehicle 1 is provided with a front seat 4 and a rear seat 5 on a floor 3 of a vehicle interior 2, and a luggage compartment 6 is provided behind the rear seat 5 in the vehicle interior 2.

The front and rear middle parts of the floor 3 are bent so that the front part of the floor 3 is on the lower side and the rear part is on the upper side. A seat cushion 5a of the rear seat 5 is placed on the rear upper surface of the floor 3, and the seat cushion 5a is rotatable back and forth via a first pivot shaft 7. Further, the seat back 5b of the rear seat 5 is pivotally supported by the seat cushion 5a so as to be rotatable back and forth. That is, a fixing member 8 is attached to the seat cushion 5a, a rotating arm 10 is pivoted to the fixing member 8 via a second pivot shaft 9, and a seat back 5b is attached to the rotating arm 10. There is.

On the other hand, a pair of left and right locking devices 12 are provided at the pivot points between the seat cushion 5a and the seat bag 5b to lock the seat bag 5b in a predetermined inclined position and to release the lock. This lock device 12 has a lock operating lever 13 pivotally supported by the fixing member 8, and an engaging protrusion 13a is formed on the lock operating lever 13.
An engagement recess 10a that elastically engages with the engagement protrusion 13a is formed in the rotating portion of the rotating arm 10. Then, the engagement protrusion 13a and the engagement recess 10a engage with each other in a predetermined inclined posture of the seat bag 5b, and this inclined posture is maintained (as shown by solid lines in the figure). on the other hand,
By operating the lock operating lever 13, the engaging protrusion 13a
When the engagement between the engagement recess 10a and the seat back 5b is released, the seat back 5b can be rotated. (Indicated by a dashed-dotted line in the figure).

The rear seat 5 has a seat back 5b.
are folded so as to overlap on the seat cushion 5a, and from this state can be rotated forward about the first pivot shaft 7 to stand up. in this case,
The lower end of the upright rear seat 5 is configured to abut on a center tunnel 14 formed in the floor 3.

On the other hand, a locking band 17 is provided on the inner wall of the center pillar 16 of the vehicle body. One end of this locking band 17 is connected to the inner wall with a screw 18, and the other end releasably locks the lock operating lever 13 of the rear seat 5 in the upright position, thereby maintaining this upright position.

According to this invention, a locking member is provided on the fixed side of the vehicle body, and the locking member detachably locks the lock operation lever so as to maintain the upright position of the folded seat. When storing the folded seat in an upright position,
The lock operation lever provided on this seat is effectively utilized. Therefore, there is no need to provide a separate member to the seat to hold it in an upright position. As a result, the structure for holding the rear seat in an upright position is simplified, and the appearance of the seat is also improved.
