Characterize.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a safety front seat that can ensure the safety of passengers in the rear seats of a vehicle.

[0002]

[Prior art]

 Conventionally, when a vehicle has a frontal collision, the rear passengers in the vehicle may be hit against the rear surface of the front seat if the collision speed is high. In this case, if a human body hits the metal frame inside the front seat strongly, the occupant will be seriously injured.

Therefore, recently, in order to deal with this problem, a front seat equipped with an airbag for a rear seat occupant has begun to be commercially available. Also, in order to protect the heads of passengers in the rear seats in the event of a collision, a soft pad has been developed between the upper skin of the front seat and the frame between the skin and the frame.

[0004]

[Problems to be solved by the device]

 However, a front seat equipped with an airbag requires a robust frame structure that can withstand a large instantaneous load that occurs when the airbag is activated, in addition to a significant increase in weight and price. There is a problem that the adjuster mechanism such as the reclining and slide of each part of the front seat cannot be set. The robust front seat structure itself also contributes to the weight increase. In addition, a soft pad in the upper part of the seat back has a problem that it does not sufficiently absorb energy at the time of a collision, and there is a problem that knee protection is not considered at all. .

The present invention has been made in view of the above circumstances, and does not cause a significant increase in weight or price, and can be equipped with an adjuster mechanism. Furthermore, the impact at the time of a collision can be provided on the head and knees. The purpose is to provide a safety front seat that can absorb energy sufficiently and is safe.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an energy absorbing material formed from a foam or elastomer such as urethane or synthetic resin covered with a skin or a resin garnish so as to cover the entire area of the back surface. It is characterized in that members are attached.

[0007]

[Action]

 With the above configuration, the energy absorbing member made of foam or elastomer such as urethane or synthetic resin, which is attached to the entire area of the back surface, makes the head and knees of the rear seat occupant at the time of a collision as well. Effectively absorbs impact energy in the air.

[0008]

【Example】

 An embodiment according to the present invention will be described below with reference to the drawings. 1 (a) and 1 (b), an energy absorbing member 2 made of, for example, urethane foam is provided on the entire back surface of a seat back of a front seat 1 of an automobile (excluding a headrest portion), a skin or a resin. It is attached while being covered with garnish 3. This attachment may be performed by engaging a locking member such as a resin clip 5 or a metal piece 6 with the frame 4, as shown in FIGS.

As a method of manufacturing this energy absorbing member, for example, the method shown in FIG. 3 can be adopted. That is, the skin or the resin garnish 3 is set in advance between the upper mold 7 and the lower mold 8 for molding, and the raw material 9 of urethane as the energy absorbing member is added and molded. Thus, the skin or resin garnish 3 and the energy absorbing member can be integrally molded. At this time, the resin clip 5 and the metal piece 6 described above may be integrally molded.

Further, as a shape devise at this time, the head and chest colliding parts (A part in FIG. 2A), which may be fatal if a large impact is applied, are thick, and even fatal injuries occur. It is possible to set that the knee area (B area in FIG. 2A) that is not present is thin. The outer skin or the resin garnish 3, the resin clip 5 or the metal piece 6 as the locking member may be attached (bonded or the like) after the energy absorbing member 2 is molded. As the energy absorbing member 2, in addition to urethane foam, synthetic resin foam or elastomer may be used.

FIG. 4 shows the load characteristic (compressive stress-deflection characteristic diagram) of the energy absorbing member 2 according to the present invention, and the characteristic of the energy absorbing member 2 is as shown by the line a. Of the energy absorbing member 2 according to the present invention in comparison with a soft pad (characterized by line b) used as a cushioning material for the seat back and a resin garnish (characterized by line c) used as a back board. It can be seen that the energy absorption characteristics are remarkably excellent. Further, the energy absorbing member 2 according to the present invention is lightweight and inexpensive, and the adjuster mechanism can be equipped without any problems.

[0012]

[Effect of device]

 As described above, according to the present invention, it is possible to improve the safety of the occupant in the rear seat and to set the seat adjuster of each part under a lightweight and inexpensive means. In the above, it can be extremely excellent.
