JPH10278648A - Car head rest with whiplash preventing mechanism - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a head rest of a car which works in response to an impact applied from the back of the car in the event of collision and functions to prevent getting a whiplash. SOLUTION: When an impact is applied from the back of a car in the event of collision, a fixture 5 is disengaged by the inertia of a weight 3, and the upper part of a head rest is tilted forward by the force of a spring 4 so as to support the head back part of the person on the seat, thereby preventing the risk of getting a whiplash.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headrest mounted on an upper portion of a backrest of an automobile seat.

[0002]

2. Description of the Related Art Conventionally, there is a headrest, but there is almost no contact with the head during riding except for use during sleep in the vehicle. In fact, conventional headrests are not enough to prevent whiplash, especially in light of the fact that whiplash occurs frequently in rear-end collisions.

[0003]

SUMMARY OF THE INVENTION The present invention relates to an automobile accident,
In particular, it is designed to prevent whiplash that occurs frequently in rear-end collisions.

[0004]

When an impact occurs from the rear of the vehicle, such as in a rear-end collision, the column (1) fixed to the upper part of the seat moves forward with the vehicle, but the weight (3) stays at that location due to inertia. In order to try, the fixture (5) attached to the frame (2) that moves in a pendulum with respect to the column (1) is displaced rearward from the column (1), and at the same time, the frame (2) covered with the cushion material (6). ) The upper part is tilted forward by the tension spring (4). As a result, the upper portion of the cushioning material (6) is applied to the back of the occupant's head, preventing the occupant's head from warping backward and preventing whiplash.

[0005]

Embodiments of the present invention will be described below. (A) A frame (2) having a weight (3) at the lower portion is attached to a support (1) so as to move like a pendulum. (B) Both ends of the tension spring (4) are fixed to the column (1) and the frame (2), respectively, so that the frame falls forward when contracted. At this time, the fixing positions of both ends of the tension spring (4) are preferably shifted back and forth so as to ensure that the frame (2) falls forward. A kick spring may be used instead of the pull spring (4) at the joint between the column (1) and the frame (2). (C) At the lower left and right ends of the frame (2), fixtures (5) are provided so that the frames (2) stand upright and are fixed to the columns (1), resisting the tension springs (4). At this time, the fixture (5)
The frame (2) is preferably provided so as to be fixed to the rear portion of the column (1) so that the lower portion of the frame (2) does not come out of the column (1). Further, a magnet is suitable for the fixture (5). (D) Wrap the frame (2) with the cushion material (6). It is preferable that the upper portion of the cushion material is formed into a trough so as to wrap the back of the head during operation. In addition, the lower part of the column (1) is not covered with a cushion material so that the frame (2) covered with the cushion material (6) can be reliably moved forward and at the same time the height can be adjusted from the seat back. In addition, the frame (2)
It is good to make a cut in the cushioning material or to cover only the frame (2) so that the pillar (1) does not interfere when the vehicle falls forward. The headrest constructed as described above is fixed by inserting the lower part of the column (1) into the upper part of the seat.

[0006]

According to the present invention, it is possible to prevent whiplash occurring frequently due to an impact from behind the vehicle such as a rear-end collision. In addition, since it operates by physical action, it does not require power,
Even in the case of a minor accident or malfunction, it is possible to easily return to the state before the operation by hand.

Claims (1)

[Claims] 1. A pull spring (4) for attaching a frame (2) having a weight (3) at a lower portion thereof to a column (1) so as to move like a pendulum, and for causing the frame (2) to fall forward when contracted.
An automobile headrest provided with a fixture (5) for resisting a tension spring (4) and erecting a frame (2) to fix the frame (2) to a support (1), and covering at least a portion of the cushion (6) in contact with the head.
