Regarding equipment.

[Conventional technology]

The elastic support device for a sliding seat cushion provided in a conventional automobile as a vehicle is the third type of elastic support device.
As shown in the cross-sectional view of the figure, the seat cushion 1
A spring-loaded support member 3 is directly connected to a cushion frame 2.

That is, on the floor 5 in the vehicle interior, a slide adjuster 4 consisting of a rail 4a fixed to the floor 5 and a movable member 4b that can slide along the rail 4a on the upper part of the rail 4a is installed at the front and rear of the vehicle. Be prepared for the direction.

The cushion frame 2 is connected to the movable member 4b of the slide adjuster 4 by bolts (not shown) or the like.

The cushion frame 2 has a U-shaped cross section with an open inner side.
One end of each coil spring 3a of the spring-containing support member 3 is coupled to the left and right lower surfaces of the spring support member 3 at the same height level as the lower surface.

The spring-loaded support member 3 is made up of a central net-like portion 3b and a plurality of coil springs 3a, each of which has one end connected to the lower left and right surfaces of the cushion frame 2 and the other end connected to the left and right sides of the net-like portion 3b. It is configured. A cushion pad 6' is mounted on the cushion frame 2 and the spring-loaded support member 3.

This pad 6' is supported by the cushion frame 2 at its peripheral portion, and when an occupant is seated on the seat cushion 1, the pad 6'
As the spring-loaded support member 3 deforms, the load of the occupant is supported via the spring-loaded support member 3 while also deforming.

In the figure, reference numeral 7 indicates the seat cushion cover, and 8 indicates the passenger's hip point.

[Problem that the invention attempts to solve]

However, in the conventional sliding type elastic support device for a seat cushion, when trying to lower the hip point 8 of the seat cushion 1 in order to secure head clearance in the vehicle interior, the thickness of the cushion pad 6' is not sufficiently thick. There is a problem that it is not possible to secure the

In other words, the lower surface of the pad 6' is limited to the height of the spring-loaded support member 3, while the height of the spring-loaded support member 3 is such that the cushion frame 2 to which the spring-loaded support member 3 is attached can slide. Since it is limited by the height of the upper end surface of the adjuster 4, it cannot be set lower than a certain level. Therefore, in order to lower the hip point 8, the height of the lower surface 6'a of the pad 6' whose minimum height is regulated remains the same;
Only the height of the upper surface of the pad 6' is reduced, making it impossible to ensure a sufficient pad thickness.

The present invention attempts to solve the above-mentioned problems, and aims to provide an elastic support device for a sliding seat cushion that can lower the hip point while ensuring a sufficient thickness of the cushion pad. shall be.

[Means for solving problems]

Therefore, the sliding elastic support device for a seat cushion of the present invention includes a slide adjuster for adjusting the longitudinal position of the seat cushion between the floor of the vehicle and the seat cushion, and a slide adjuster for adjusting the longitudinal position of the seat cushion. The slide adjuster is comprised of a rail fixed to the floor and a movable member that can slide along the rail. A cushion frame is provided which is integrally coupled with the movable member, and the upper horizontal surface portion of the cushion frame is fixed to the lower surface of the cushion frame, and the overlay has a bent portion that is bent downward from the upper horizontal surface portion and hangs down. The present invention is characterized in that it includes a hang bracket, and the spring-loaded support member is coupled below the bend of the overhang bracket.

[Effect]

In the above-mentioned elastic support device for a sliding seat cushion of the present invention, the spring-loaded support member is bent downward from the upper horizontal surface of the overhang bracket whose upper horizontal surface is fixed to the lower surface of the cushion frame. Since it is connected to the lower part of the hanging fold, the lower surface of the seat cushion can be set further downward.

〔Example〕

Hereinafter, a sliding type elastic support device for a seat cushion as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a cross-sectional view thereof, and Fig. 2 is a perspective view of the seat cushion portion from the rear left. It is.

As shown in FIGS. 1 and 2, as in the conventional case, on the floor 5 in the vehicle interior, there is a rail 4a fixed to the floor 5, and a movable member that can slide along the rail 4a on the upper part of the rail 4a. A slide adjuster 4 consisting of a slide adjuster 4b is provided toward the front-rear direction of the vehicle.

The cushion frame 2 is connected to the movable member 4b of the slide adjuster 4 by bolts (not shown) or the like.

Further, the cushion frame 2 has a U-shaped cross section with an open inner side, and spring-loaded support members 3 are attached to the left and right lower surfaces of the cushion frame 2 via overhang brackets 9.

That is, the overhang bracket 9 has an upper horizontal surface 9a fixed to the lower surface of the cushion frame 2 by welding or the like, and a lower horizontal surface 9b set at a position appropriately lower than the upper horizontal surface 9a. One end of each coil spring 3a of the spring-containing support member 3 is coupled to the lower horizontal surface 9b of the overhang bracket 9.

Note that the other parts are configured almost in the same manner as conventional ones.

In other words, the spring-loaded support member 3 is made up of a central net-like portion 3b and a plurality of coil springs 3a, each of which has one end connected to the lower left and right surfaces of the cushion frame 2 and the other end connected to the left and right sides of the net-like portion 3b. It is configured. A cushion pad 6 is mounted on the cushion frame 2 and the spring-containing support member 3.

This pad 6 is supported by the cushion frame 2 at its peripheral portion, and when an occupant is seated on the seat cushion 1, the pad 6 deforms and the spring-loaded support member 3 also deforms, and the load of the occupant is applied. is supported via a spring-loaded support member 3.

In addition, the reference numeral 6a in the figure indicates the lower surface of the pad 6, and 6'a
10 indicates the lower surface of the conventional pad, and 10 indicates the seat back.

Since the elastic support device for a sliding seat cushion as an embodiment of the present invention is configured as described above, the seat cushion 1 can be moved along the rail 4a of the slide adjuster 4 in a predetermined range together with the movable member 4b. It can be moved freely back and forth within the room, and can be set to an appropriate forward or backward position. The seat cushion 1 is fixed in its longitudinal position by a stopper (not shown).

When an occupant sits on the seat cushion 1, the cushion pad 6 supports the occupant, and the pad 6 is elastically supported by the spring-loaded cushion member 3.

Furthermore, in this embodiment, the cushion pad 6
can be made thicker than before.

In other words, by overhang bracket 9,
Since the height of the spring-loaded support member 3 can be lowered, the lower surface 6a of the pad 6 can be adjusted according to the height of the support member 3.
The lower surface 6'a of the pad can be made lower than the conventional pad lower surface 6'a, and therefore the pad thickness can be increased.

In this way, the thickness of the cushion pad 6 can be made larger than that of the conventional cushion pad, so that riding comfort can be improved.

Furthermore, since the hip point 8 of the seat cushion 1 can be lowered while ensuring a sufficient pad thickness, even if the hip point 8 is lowered, the seat cushion performance with sufficient riding comfort can be ensured.

[Effect of idea]

As described in detail above, according to the elastic support device for a sliding seat cushion of the present invention, the following effects and advantages can be obtained with a simple configuration.

(1) Since the spring-loaded support member is connected to the lower part of the overhang bracket whose upper horizontal surface is fixed to the lower surface of the cushion frame, the spring-loaded support member is bent downward from the upper horizontal surface and hangs down. The height of the spring-loaded support member can be lowered, and as the height of the spring-loaded support member is lowered, the lower surface of the pad can be lowered to the extent that the pad thickness can be increased, improving riding comfort. .

(2) For the same reason as in (1) above, lowering the hip point of the seat cushion has the effect of ensuring cushion performance with sufficient riding comfort.
