Embodiment Construction

[0186]Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Note that the components, arrangements, and the like described below are not intended to limit the present invention, and various modifications can be made in accordance with the spirit of the present invention. In addition, in this specification, the ride refers to a ground running ride having wheels such as an automobile and a train, and a moving ride to which a seat can be attached, such as an airplane or a ship moving outside the ground. In addition, the general seating load includes a seating shock generated when seated, a load during acceleration due to a sudden start of a seated object, and the like. In addition, the load at the time of a rear collision refers to a large amount of load caused by a rear collision, a severe rear-end collision of the passenger from the rear side, a large collision during reverse driving, and the like. Does not include loa...

Abstract

A vehicle seat allows, using a simple structure independent of a headrest, the entire body of the occupant sitting on the vehicle seat to sink (move) a large amount toward the rear of the vehicle when a rear collision occurs, and thus the vehicle seat can effectively reduce an impact to the occupant in the rear collision. A vehicle seat (S) is provided with: a seatback frame (1); a headrest (S3); a pressure receiving member (20) which is movable independently of the headrest (S3); and a rotation member (30) which is provided to either one and / or the other of side sections on both sides of the seatback frame (1), is connected to the pressure receiving member (20), and moves independently of the headrest (S3) due to a predetermined impact load. The rotation member (30) is connected to a pressing means (35) which press the pressure receiving member (20) to the front side of the seatback frame (1) through connection members (21, 22). The force required to return the rotation member (30) to an initial state is set in a range in which the force is greatest when the occupant is seated normally and the force is small when the rotation member (30) moves due to a rear collision.

Description

technical field [0001] The present invention relates to an occupant seat, and more particularly, to an occupant seat that realizes cushioning in a rear collision. Background technique [0002] Generally speaking, when the rear part of a vehicle or other vehicle is rear-ended, or is hit by a collision while driving in reverse, that is, a rear collision, the head of the seated passenger is rapidly tilted backward due to inertial force, and the neck is impacted. question. [0003] Therefore, in order to protect the head or neck of the passenger from the shock caused by the rear collision and reduce the shock to the neck, the seat back is provided above the seat back to receive the shock from the rear. A headrest for the passenger's head. [0004] However, only providing the headrest can not only reduce the impact on the body, but also cannot reduce the distance between the passenger's head and the headrest rapidly and sufficiently reduce the impact on the neck in the event of...
