Abstract

(57) [Summary] [Purpose] In a coupe-type vehicle, while protecting the occupant from the inward protrusion of the vehicle body door due to a side collision, the passenger occupancy of the rear seat occupant is improved. A receiving body, which is integrally joined to a seat back frame disposed in the seat back and is projected to the upper side of the seat back, is mounted to a vehicle body door that projects into the vehicle interior due to a side collision. Since it is possible to suppress the movement of the vehicle body door which is deformed by supporting the vehicle body and to support the vehicle body door, it is possible to protect the shoulders and arms of the occupant which are unavoidably projected outward from the seat back due to the shape of the seat.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of the structure of a seat in an automobile, particularly a coupe type vehicle.

[0002]

[Prior Art]

 Conventionally, sports-type seats are often used as front seats in automobiles, especially in coupe-type vehicles, because of the characteristics of the vehicle. In order to minimize the change in the vehicle and to ensure the maneuverability of the vehicle, the width is narrowed so as to mainly hold the occupant's thighs, waist and back.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional type, a sports-type automobile seat that is used for the purpose of minimizing change in the driving posture of the occupant during driving and ensuring reliable vehicle maneuverability is mainly used. Since it is made narrower to hold the occupant's thighs, waist and back, the posture change of the occupant is reduced and the maneuverability during driving of the vehicle is ensured as in the above purpose. However, since this sports-type automobile seat aims to minimize the posture change of the occupant driving as described above, the shoulders and arms of the occupant who steer the steering wheel are It is designed to be as free as possible, which inevitably causes the shoulders and arms of the occupants to project outward from the seatback, and in the event of a collision from the side of the vehicle, this collision vehicle When the vehicle door by an impact force applied causes the protruding into the passenger compartment side, there is a drawback that the risk of the vehicle door which protrudes into the passenger compartment side of this injure against occupant's shoulder or arm is raised.

Further, in a coupe-type vehicle, when a passenger seated in the rear seat gets on and off, the front seat is used as a clue to get on and off, but when the passenger gets on and off, the seat back of the front seat is used. The passengers must be defeated to secure a space for the passengers to get on and off, which forces the passengers to take a cramped posture, and it is not possible to get on and off the vehicle safely and swiftly.

Therefore, a headrest provided on the upper portion of the seat back is provided with grip portions on both sides of the cushion, which is a hollow core body (Actually No. 59-2245), and a rear side of the seat back along the vertical direction. Although a support member provided with a supporting member (No. 58-9839) is proposed, in the case of No. 59-2245 No. 59-24539 and No. 58-9839 No. 58-9839, it is used only for passengers getting on and off. It is not provided for the purpose of protecting the occupant in the event of a side collision of the vehicle body, and the risk of injury to the occupant due to the protrusion of the vehicle body door toward the passenger compartment in the event of a side collision. The degree is the same as the conventional one.

Therefore, the present invention solves the drawbacks of the above-mentioned conventional ones, and prevents the risk of injury to an occupant due to the protrusion of the vehicle body door toward the vehicle interior caused by the impact force generated by the side collision of the vehicle body. The aim is to improve the convenience of getting in and out of the seat back by using the receiving body that projects to the upper side of the seat back as a grip portion.

[0007]

[Means for Solving the Problems]

 Therefore, together with the seat cushion, both ends of the rod-shaped member are joined to the seat back frame arranged in the seat back that constitutes the automobile seat, and part of the rod-shaped member is placed on the vehicle body door side from the upper side of the seat back. It is formed by protruding to form a receiver.

[0008]

[Action]

 With the above configuration, when the bumper of the collision vehicle collides with the vehicle body door of the vehicle to be collided, and the vehicle body door located closest to the side of the occupant is projected into the vehicle interior, The receiving body formed of a rod-like member that projects from the upper side of the seat back that constitutes the seat and has both ends integrally joined to the seat back frame disposed in the seat back projects due to the side collision. Since it abuts on the vehicle body door, the load from the vehicle body door is supported by the entire seat back frame via the grips, and the vehicle body door protruding toward the inside of the vehicle is received. Even if the shoulders and arms of a seated occupant project outward from the seat back, it can be protected.

Further, even when the passenger seated in the rear seat gets out of the passenger compartment, even if the seat back of the front seat is tilted, the grip portion protruding to the upper side of the seat back of the front seat is used as a clue. Since it is possible to maintain the posture after disembarking, it is possible to disembark safely and quickly, and at the same time when riding, you can hold the posture while holding the receiving body. Also, by holding this grip portion, the seat back in which the front seat is tilted can be easily and quickly tilted up and down.
