Abstract

PURPOSE:To assure sufficient luggage storing space by providing a rear seat with separate right and left seat backs and, only when one of the seat backs is operated to be inclined forwardly, permitting release of a locking mechanism for a reclining mechanism of the other seat back. CONSTITUTION:When a right seat back 4a is kept in its standing position, a lock plate 14 provided at the rear lower end of the right seat back 4a is engaged with a reclining stopper 16, so that a knuckle lever 18 connected to the stopper 16 through a locking lever 19 cannot be pivoted upwardly, preventing rearward inclination of a left seat back 4b. On the contrary, when a lock release knob 12 is pulled up to release engagement of a lock member 11 with a lock pin 10 and thereby to forwardly incline the right seat back 4a, the lock plate 4 moves away forwardly, releasing engagement with the stopper 16. This permits operation of a reclining mechanism 13 to rearwardly incline the left seat back 4b.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rear seat device suitable for automobiles, particularly commercial vehicles.

(Prior art) It is generally known that in commercial vehicles such as pan-type and wagon-type commercial vehicles, the seat back of the rear seat can be tilted forward as necessary to expand the cargo space behind the rear seat. There is. On the other hand, in general passenger cars,
For purposes such as reducing fatigue when sitting for long periods of time,
A reclining mechanism in which the rearward inclination angle of the seat back can be adjusted and held in stages is also commonly used (for example, see Japanese Utility Model Application Publication No. 56-53642).

However, in general commercial vehicles, when a reclining mechanism is adopted for the rear seats, the cargo space is narrowed due to the seat back tilting backwards, making it difficult to use the vehicle as a commercial vehicle. The problem is that it is difficult to improve.

(Objective of the Invention) An object of the present invention is to improve the comfort of rear seats without narrowing the space that can be used as a luggage compartment of an automobile.

(Structure of the Invention) An automobile seat device for achieving the above object of the present invention divides a seat pack of a rear seat into left and right parts, supports one seat pack so that it can be folded forward with respect to a seat cushion, and supports the other seat pack so that it can be folded forward. A reclining mechanism is provided on the seat back of the seat pack, and a locking member is provided on the one seat pack for locking the reclining mechanism of the other seat pack when the seat pack is in an upright state.

The seat pack is characterized in that the lock is released only when the one seat pack is operated toward the front, and the other seat pack can be reclined.

In other words, in the case of the above rear seat device, in order to operate the reclining mechanism, one seat pack must be folded forward, and even if the other seat pack is tilted backwards, the luggage storage space behind it is narrowed. By folding one of the seat packs forward, a luggage storage space is created above the folded seat pack.

(Effects of the Invention) Therefore, according to the present invention, when operating the rear seat reclining mechanism, one of the seat packs must be folded forward, so the space above the folded seat pack can be used as a luggage storage space. 1. When the present invention is applied to a commercial vehicle, the passenger cannot arbitrarily narrow the luggage storage space, and while ensuring sufficient luggage storage space, the reclining mechanism can be used to improve the comfort of the rear seats. can be improved.

(Embodiment) An embodiment of the automobile rear seat device of the present invention applied to a commercial vehicle will be described below with reference to the drawings.

In the car l shown in Fig. 1, 2 is a front seat;
3 is the rear seat, and seat pack 4 of rear seat 3
When the rear seat 4 is raised up against the seat cushion 5, the rear part of the rear bag 4 can be used as a luggage compartment 6.

Now, in the rear seat 3, the seat cushion 5 is fixed to the floor 7 of the vehicle body, and the seat pack 4 is composed of a right seat back 4a and a left seat back 4b, which are divided at the center in the width direction of the vehicle, as shown in FIG. has been done. The right seat back 4a is supported by seat brackets 8a and 9a on both sides of the seat so that it can be tilted forward relative to the seat tension 5, and the left seat back 4b is supported by seat brackets 8b and 9b on both sides of the seat so that it can be tilted backwards. ing. In this case, the right seat back 4a has a lock member 11 that engages with a lock bin 1o that protrudes from the side wall of the vehicle body at its upper right end, and a lock release knob 12 that releases the engagement of this lock member 11 with the lock bin 10. and is held in an upright position by this engagement.

By releasing the engagement, it can be folded forward. On the other hand, the left seat back 4b is supported by the seat bracket 8b via a reclining mechanism 13, and can be tilted rearward only when the right seat back 4a is folded forward.

That is, as shown in FIGS. 3 and 4, a lock plate 14 is provided at the lower end of the back surface of the right seat back 4a and protrudes toward the left seat back 4b, and a step portion of the floor 7 below the lock plate 14 is provided. 7a Fixed bracket 1
5, a reclining stopper 16 whose upper end engages with the front surface of the lock plate 14 is supported by a pin 17 so as to be rotatable forward. On the other hand, left seat back 4b
In the reclining mechanism 13, a knuckle lever 18 that unlocks a sector (not shown) that adjusts the rearward tilt angle of the left seat back 4b protrudes forward, and a locking lever integrated with the knuckle lever 18. 19 protrudes downward. The lower end of the reclining stopper 16 and the lower end of the locking lever 19 are connected by a lock 20.

Therefore, in the rear seat device of the above embodiment, when the right seat back 4a is held in the upright state, the lock plate 14 is engaged with the reclining stopper 16, and the locking lever 19 is engaged with the reclining stopper 16. The knuckle lever 18 connected thereto cannot be rotated upward, and the left seat back 4b cannot be tilted rearward. Therefore, when the right seat back 4a is pulled up, the locking member 11 The engagement with the lock bin 10 is released, and it becomes possible to fold forward. When the right seat back 4a is folded forward, the lock plate 14 escapes forward and upward, and the engagement of the reclining stopper 16 is released. Therefore, the knuckle lever 18 of the reclining mechanism 13 is rotatable, and the left seat back 4b can be moved rearward at a desired angle by operating the knuckle lever 18.

That is, by folding the right seat back 4a forward, a luggage storage space is formed above it.

If the left seat back 4b is not tilted backwards, the baggage storage space will be expanded, and even if the left seatback 4b is tilted backwards, the right seatback 4a will be tilted forward, resulting in an additional baggage storage space. Because of this, the luggage storage space of the entire vehicle does not become narrower than when both seat backs 4a and 4b are erected.

In the above embodiment, when the right seat back is raised, the operation of the reclining mechanism itself is locked, but when the right seat back is raised between the left and right seat backs, the left seat back itself is prevented from tilting backwards. A locking member may be provided to indirectly lock the reclining mechanism.
