Abstract

PURPOSE:To extend a cargo room, by providing a slender plate between the back of a seat and a cargo floor and fitting the plate with hinges so that the gap between the back of the seat and the cargo floor can be closed. CONSTITUTION:A slender plate 8 is provided between the back 5 of a rear seat and a cargo floor 2. The front and rear side edges of the plate 8 are coupled by hinges to brackets 6, 7 secured on the lower part of the back 5 of the seat and the cargo floor 2. The ends of springs 11 are anchored to the right and left ends of the plate 8 and the other ends of the springs are secured on a slope between the seat floor 1 and the cargo floor 2 to always urge the plate downwards.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for a rear seat of an automobile, which is installed in a hatchback type passenger car or the like.

In general, hatchback type cars have a luggage compartment behind the rear seats, which can be expanded depending on the amount of luggage to be loaded by folding the rear seats forward. It is desirable that the However, in this case, if the seat back were simply folded down onto the seat cushion, a level difference would be created between the back of the seat back and the cargo platform lid, which is not desirable.

Therefore, in conventional rear seat support devices, the lower front surface of the seat cushion is pivoted to the seat floor, and the lower side of the seat back is double-hinged to the seat floor, allowing the seat cushion to remain as it is. The seat back can be folded down onto the seat cushion around one hinge axis, and after the seat cushion has been erected and rotated forward, the seat back can be folded down around the other hinge axis onto the seat floor. It is also possible to make the back surface and the loading platform floor almost on the same plane.

By the way, if you want the seat back to be able to fold down both onto the seat cushion and onto the seat floor, the seat back must have two hinge shafts, so that when the seat back falls forward, the lower end of the seat back Because the position changes,
There is a problem in that a gap is created between the lower edge of the seat back and the front edge of the cargo bed floor, and small items tend to fall into the gap. Therefore, in conventional support devices of this type, the mat on the cargo bed floor is stretched forward and fixed to the back of the seat back.
There is one that closes the gap between the seat barrier and the cargo floor.

This invention is not a method using a floor mat as described above, but a support device for a rear seat of an automobile that can prevent small items from falling into the gap between the seat back and the floor of the cargo area. In the case where both the cushion and the upper part of the seat floor can be folded down,
A band-shaped plate member is disposed between the back of the seat back and the cargo floor, and the plate member is hinged to the back of the seat back and the cargo floor to close the gap between the seat back and the cargo floor. It is an object of the present invention to provide a supporting device for a rear seat of an automobile.

An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show a support device for a rear seat of an automobile according to an embodiment of the present invention. In the figures, 1 is a seat floor of a vehicle body, and behind the seat floor 1 is a seat floor 1.
Continuing with this, the loading platform floor 2 is formed higher than that, and above the seat 1 is on the left.

A rear seat 3 divided on the right side is provided. The rear seats 3 each include a seat cushion 4 placed substantially horizontally on the seat straighter 1, and a seat back 5 placed upright at the rear end of the seat cushion 4.

The lower front surface of the seat cushion 4 is pivotally supported by the front end of the seat frame 1, and a belt-shaped plate extending in the width direction of the seat back 5 is provided between the seat back 5 and the cargo platform 70a 2. A member 8 is provided, the front and rear ends of which are hinged to a bracket 6.7 fixed to the lower back of the seat No. 7 truck 5 and to the platform floor 2, respectively. Further, one end of a spring member 11 is secured to the lower surface of the plate member 8 on both the left and right sides thereof, and the other end of the spring member 11 is attached to an inclined portion 12 between the seat floor 1 and the cargo platform 70a2. The spring member 11 urges the plate member 8 downward. Further, the plate member 8 is formed with a large number of rectangular four portions 8b arranged in the width direction. Further, a locking device 14 is provided between the seat back 5 and the vehicle body 13 for locking the seat back 5 to the vehicle body 13 in the normal upright state.

Next, the operating method of this device will be explained using FIG.

First, when a passenger sits on the rear seat 3, place the seat cushion 4 horizontally on the seat 70a1, place the lower end of the seat back 5 on the rear end of this seat cushion 4, and place the seat cushion 4 horizontally on the seat 70a1. The upper part of the vehicle body 1 is locked by the locking device 14.
All you have to do is lock it at 3.

Then, the plate member 8 is pulled downward by the spring member 11 while being positioned on the same horizontal plane as the loading platform floor 2, whereby the seat back 5 is fixed and held in the substantially upright state shown in FIG. 3(a). That will happen.

Moreover, when expanding the luggage compartment space, the seat back 5 may be folded forward after the locking device 14 is operated to release the engagement between the seat back 5 and the vehicle body 13. Then, the plate member 8 rotates upward around the hinge axis on the cargo platform floor 2 side against the spring force of the spring member 11, and at the same time, the seat back 5 falls down onto the seat cushion 4, and its back surface becomes the third
It is in a slightly tilted state as shown in Figure ('b). In this way, the luggage compartment space will be expanded.

In addition, if you want to expand the cargo space and make the seat back 5 and the cargo platform 70a 2 on the same plane, after rotating the seat cushion 4 forward about the uniaxial fulcrum on its front lower surface, All you have to do is fold the seat tsukutsuku 5 forward.

Then, the truck 5 is placed directly on the seat floor 1, and as a result, the back of the seat back 5, the plate member 8, and the cargo floor 26 are all on the same horizontal plane as shown in FIG. 3(C). It will be located.

The device of this embodiment as described above is very convenient because the seat back can be folded down onto the seat cushion or onto the seat floor when expanding the cargo space. Moreover, since the gap between the seat back and the cargo bed floor is always closed by the plate member, small items will not fall into it.

Furthermore, this device has a very simple structure because the plate members are only hingedly connected to the back surface of the seat back and the floor of the cargo platform.

In the above embodiment, a split-type rear partial seat support device has been described, but the present invention can be similarly applied to an integrated rear seat support device.

As described above, according to the support device for a rear seat of an automobile according to the present invention, a belt-shaped plate member is disposed between the back of the seat back and the cargo floor, and the plate member is hinged to the seat back and the cargo floor, respectively. Since they are combined, it is possible to close the gap between the seat back and the cargo bed floor with a simple structure and prevent small items from falling into it.Furthermore, the seat back can be folded down onto the seat cushion or placed directly on the seat floor. It also has the effect of making the floor of the expanded luggage space flat.
