Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a car seat.

BACKGROUND ART An automobile seat (hereinafter referred to as a seat) B has a seat frame 10 on which a spring material (not shown) such as a coil spring or an S spring is placed, and a sheet-like material is placed on the seat frame 10, as shown in FIG. Support pad (not shown)
The main pad 11 made of foam material, lock material, etc. is placed on top of the main pad 11, and a cover pad 13 is placed on the surface of the main pad 11 in order to create an uneven pattern on the skin 12 and provide a good tactile feel.
is laid down and finally covered with a skin 12 made of vinyl, woven fabric, leather, etc.

Further, as shown in FIG. 3, deep grooves 1 are formed in the epidermis 12.
2' is formed by bending, and a foamed resin is used for the cover pad 13, and this foamed resin is applied to the outer skin 12.
There is also a sheet B' which is foamed along the curved shape of the sheet and has block-shaped protrusions 14 formed at arbitrary positions on the sheet surface. An example of a sheet B' having a block-shaped convex portion 14 on its surface is a seat for an automobile or the like disclosed in Japanese Utility Model Application Publication No. 47-21319.

Problems to be Solved by the Invention Seat B shown in Figure 2 has the problem that when an occupant sits on Seat B, the entire surface of Seat B comes into contact with the body, which causes stuffiness when sitting for a long time. It was hot. Additionally, if the entire surface of Seat B comes into contact with the body, the seat will also come into contact with areas other than those necessary to maintain the occupant in the correct posture when the car is in motion, which can cause fatigue if seated for long periods of time. There were also some problems. Also, the sheet shown in Figure 3
If a block-shaped convex portion 14 is provided on the surface of the seat B' as shown in B', the above two problems can be somewhat solved, but since the convex portion 14 is integrated with the seat B', Because it deforms when seated, it has not been able to achieve sufficient effects.

Means for Solving the Problem An automobile seat is provided with a substantially L-shaped first support consisting of a back support rod extending substantially vertically, and a seat support rod connected to the back support rod and extending substantially horizontally. a rod, second and third support rods arranged perpendicularly to the back support rod of the first support rod, and a fourth support rod arranged perpendicular to the seat support rod of the first support rod. and a fifth support rod, and a predetermined number of block-shaped pads each independently supported by the first to fifth support rods of the seat frame. The pads are placed only in the areas necessary to keep the occupant in the correct posture while the vehicle is running, and are not placed in other areas.

Function: When an occupant is seated on the seat, a predetermined number of pads attached to the support rods of the seat frame provide support only to the areas necessary to keep the occupant in the correct posture while the vehicle is running.

Example The sheet A according to the present invention is as shown in FIG.
A first support rod 2a having a substantially L-shape, consisting of a back support rod 2a' extending in a substantially vertical direction, and a seat support rod 2a'' extending in a substantially horizontal direction and connected to the back support rod 2a'.
and a second support rod 2b and a third support rod arranged perpendicularly to the back support rod 2a' of the first support rod 2a.
A seat frame 1 comprising a support rod 2c, a fourth support rod 2d and a fourth support rod 2e arranged orthogonally to the seat support rod 2a'' of the first support rod 2a; 1st to 5th of frame 1
A predetermined number of pads 3 are supported independently by support rods 2a to 2e. This pad 3 has a block shape as shown in the figure, and its installation position is in an insensitive part of the body, such as the lower pelvis, and in a place necessary to keep the occupant in the correct posture when driving a car. It is installed only in Further, this pad 3 can be moved by a predetermined stroke with respect to a support rod 2 that constitutes the seat frame 1.

When an occupant sits on the seat A having the above structure, the position of each pad 3 is adjusted to match the occupant's body shape before sitting down. The occupant is then maintained in an optimal posture while driving the vehicle by the action of each independent pad 3.

Effects of the invention As mentioned above, the invention provides a car seat that
Consisting of a seat frame consisting of first to fifth support rods, and a predetermined number of block-shaped pads each independently supported by the first to fifth support rods, By placing these pads only in the areas necessary to keep the occupant in the correct posture while driving, the structure has been created so that when the occupant sits on the seat, it is extremely difficult for the occupant to sit in any position other than the correct posture. It is something. The occupant is always seated in the correct posture on the seat, and this posture is reliably held by the seat, thereby significantly reducing fatigue of the occupant. Also, if the occupants are always kept in the correct posture,
When driving a car, the strain placed on the occupant's spine can be minimized and lower back pain can be prevented. or,
Each pad is independent and has good ventilation, so you won't get stuffy even if you sit on the seat for a long time.
Furthermore, the shape of the seat surface can be easily changed by moving the individual pads.
