Description

[Detailed Description of the Invention] The present invention relates to an automobile seat, and more particularly to a seat hinge that connects a backrest and a seat portion of the seat.

Conventionally, various measures have been taken in automobiles to ensure the safety of occupants in the event of a collision.

Examples of safety measures installed inside automobiles include headrests to prevent whiplash in the event of a rear-end collision, and seatbelts to keep occupants in their seats and prevent their bodies from being thrown out in the event of a collision or rollover accident. This can be cited as an example.

It is well known that all of these safety measures are effective depending on their purpose, and are now installed in most automobiles.

However, the reality is that these methods have almost no effect on collisions from the side of a vehicle.

That is, in side collisions of automobiles that tend to occur at intersections, etc., the door of the side-impacted automobile often breaks and enters the vehicle interior, causing injury to the occupants.

As a countermeasure to this problem, there is a system as shown in Utility Model Publication No. 50-5155 in which a door bracket is specially fixed inside the side frame.

However, the purpose of this invention is to provide a safety measure that can achieve the desired effect by simply changing the shape of the seat hinge, without adding any new parts, in order to prevent door entry in the event of a side collision. The gist of the present invention, which is a distant relative of this object, is that in a seat hinge that connects the backrest and the seat of an automobile seat, a A seat hinge for an automobile is characterized in that a base plate to be fixed has a shock-absorbing protrusion projecting toward the door integrally with the base plate.

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

In the drawings, FIG. 1 is a schematic perspective view showing a seat hinge 1 according to the present invention, which extends from a base plate 2 and a backrest plate 3.

This base plate 2 has a shock absorbing convex portion 4 as shown in the figure.
is raging all at once in its center.

The seat hinge 1 is connected to the backrest 1 as shown in FIG.
2 is connected to the seat portion 11 so that the angle can be adjusted, and the seat 1
It constitutes 0.

In this case, the base plate 2 is fixed to the side closer to the door 20 of both sides of the seat 11, as shown in FIG. It is designed to protrude toward the door.

In the seat hinge 1 according to the present invention having the above structure, the shock absorbing convex portion 4 provided on the base plate 2 is attached to the seat hinge 1.
By protruding toward the door from the 0 position, when the car is hit from the side, the door deforms and tries to enter the vehicle interior, that is, when the door 20 is hit from the left side in FIG. When the door deforms and tries to intrude toward the seat 10, as is clear from the drawing, the impact-absorbing convex portion 4 provided at the front-rear center of the door, which undergoes a relatively large amount of deformation, first receives the impact. This function prevents further entry into the door and protects the occupants.

The length, material, and strength of the base plate 2, as well as the position and shape of the impact-absorbing convex portion 4 provided thereon, can be arbitrarily selected depending on the required physical strength.

In the illustrated embodiment, one impact-absorbing projection 4 is provided at the center of the base plate 2, but a plurality of impact-absorbing projections 4 may be provided depending on the case.

It is preferable to attach a cover 30 having a shape as shown in FIG. 4, for example, to the base plate 2.

This cover 30 has a decorative effect by covering the base plate 2, as shown in FIG. 2, and a portion corresponding to the impact-absorbing protrusion is formed into a pocket 31 as shown in cross section in FIG. It can be used in a variety of ways, such as as a holder for storing tape cassettes.

As described above, the present invention comprises a seat hinge that connects the backrest and the seat of an automobile seat in an angle-adjustable manner, in which a shock-absorbing convex portion is provided on the base plate of the seat hinge so as to protrude toward the door. can prevent the door from entering the interior of the vehicle in the event of a side collision, thus ensuring the safety of the occupants.At the same time, the convex portion can also be used as a pocket. It is structurally inexpensive and can be manufactured extremely easily.
