A headrest(10) and the upper back rest are folded in a double-stage by a pin(15) and each hinge device formed with an elastic leaf spring(17) connecting the headrest to the upper back rest, the upper back rest to the lower back rest, and the lower back rest to a cushion(13).

Description

Two-stage folding seat for automobile {

The present invention relates to a two-stage folding seat for automobiles, and more particularly, by applying a hinge structure in the middle of the headrest and the backrest so as to be able to fold each step by step, it is easy to move from the driver's seat and the passenger seat to the rear seat during a vehicle accident. It is possible to reinforce the safety aspects, and to provide a convenience, such as the ability to relieve fatigue by placing the foot when driving for a long time, or to secure the front view of the rear passengers, etc. .

In general, the car seat can be adjusted to back and forth the headrest or the backrest itself.

On the other hand, when a car accident is difficult to secure the driver's seat and passenger seat space to move to the rear seat for safety, the current seat structure, this is sometimes unpleasant or difficult to feel sometimes.

In addition, in order to secure the front view of the rear passengers, the headrest is usually folded or completely removed, which is limited due to the height of the backrest.

In addition, you can lie down with your back fully tilted by releasing fatigue when driving for a long time. have.

Accordingly, the present invention has been devised in view of the above, and adopts a structure capable of folding the seat back in the middle and a structure capable of fully flipping the headrest forward, thereby selectively selecting the folding state of the seat as necessary. It can be easily moved from the driver's seat and the passenger seat to the rear seat in the event of a vehicle accident, enhancing safety aspects, providing a condition to lift foot and fatigue during long hours driving, and improve the front view of the rear seat passenger. It is an object of the present invention to provide a two-stage folding seat for a car that can be sufficiently secured.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a seat for a vehicle including a headrest and a backrest, separated from the upper and lower middle of the backrest to form a combination of the upper backrest 11 and the lower backrest 12 at the same time seated in the form of the top of each front 14a, 14b, and the pinrest between the headrest 10 and the upper back 11, the upper back 11 and the lower back 12, the lower back 12 and the cushion 13 It is characterized in that the headrest 10 and the upper back 11 can be folded in two stages by connecting with each hinge means consisting of 15) and the resilient leaf spring 17.

In addition, the hinge means is a hinge piece of the headrest 10, the upper back 11, the lower back 12, the pair of hinge pieces 18a and the elastic leaf spring 17 of the cushion 13 18b, the pin 15 is penetrated at the same time while the snap ring 16 is fastened to the end, characterized in that the resilient leaf spring 17 having a predetermined area is configured to support the lower back portion of each member. .

In addition, when the resilient leaf spring 17 is mounted on the rear of each member, it is mounted in a state that is wider than the curvature of the initial state is characterized in that the mounting on the rear of the member is pressed.

This will be described in more detail as follows.

As shown in Fig. 1 and 2, the seat back is divided into an upper back 11 and a lower back 12, and at the same time a pair of hinge pieces 18a are formed at each of the upper and lower ends, and the headrest Each hinge piece 18a is also formed in the lower end of 10 and the rear end of the cushion 13.

In addition, while having a pipe-shaped hinge piece 18b capable of fastening the pin 15 to one side, an elastic leaf spring 17 made of a square plate shape is provided.

At this time, the resilient leaf spring 17 is bent at a predetermined curvature and is mounted in a more open state when actually mounted, thereby exerting its own restoring force, that is, each member, that is, the headrest 10. The upper back 11, the lower back 12, and the cushion 13 can be firmly mounted in a compressed state.

In addition, seating portions 14a and 14b having a shape in which the upper part of the upper back 11 and the lower back 12 are cut out to dig a center portion or penetrate laterally are formed, and thus the headrest 10 and the headrest 10 are formed. The upper back 11 can be accommodated in the folded state.

Therefore, the hinge piece 18b of the resilient leaf spring 17 is supported while one-to-one correspondence of the hinge piece 18a of the headrest 10, the upper back 11, the lower back 12, and the cushion 13 is provided. Placed therebetween, and through these fastened through the pin 15, by inserting a snap ring 16 at the end of the pin 15, each member can be assembled in one piece while supporting the back with the resilient leaf spring (17) Can be.

As shown in FIG. 3, the seat can be flipped in stages as necessary, i.e., the headrest 10 can be flipped one step to secure the front view of the rear seat passenger, or two steps can be flipped up to the upper back 11. Sufficient visibility for the rear seat passengers, as well as the feet, can help you relax.

Particularly, if the seat is pushed back and forth in a car accident, the elastic leaf spring portion can be flipped and the whole seat can be flipped back at a time, thus securing sufficient space for movement, thereby allowing the driver or front passenger to easily move toward the rear seat. I can move it.

Of course, when the seat is used normally, each resilient leaf spring can withstand the driver's or passenger's load through the structure that the rear part between the members comes into contact with and interferes. Concerns can be ruled out.

As described above, the present invention provides a two-stage folding seat that can fold half of the headrest and the backrest step by step, thereby ensuring sufficient front vision of the rear seat passenger, and at the same time, to ease the fatigue by placing the foot during long driving. There is an advantage that can be secured to the maximum safety by securing enough space for the driver or front passenger to easily move toward the rear seat in the event of a vehicle accident.
