Embodiment Construction

[0211] Embodiments of the present invention will be described below with reference to the drawings. In addition, the components, arrangements, etc. described below do not limit the present invention, and various changes can be made according to the gist of the present invention. In addition, in this specification, a vehicle refers to a vehicle for traveling on the ground having wheels such as an automobile or a train, and a vehicle for moving such as an airplane or a ship that moves outside the ground and can mount a seat. In addition, the general seating load includes a seating impact generated when the vehicle is seated, a load during acceleration due to sudden start of the vehicle, and the like. In addition, the load at the time of the rear collision refers to a large amount of load due to the rear collision, a severe rear-end collision of a passenger from the rear side, a large collision during reverse running, and the like. Loads that do not include the same range of loa...

Abstract

By providing a simple structure that is relatively independent from the headrest, the amount of sinking (moving) of the entire sitting body including the waist to the rear side of the passenger can be increased during a rear collision, and the force exerted on the seat during a rear collision can be effectively reduced. A passenger seat for a shock to a passenger. A seat (S) for a vehicle, including a seat back frame (1), a headrest (S3), a pressure-bearing part (20) that supports the passenger's body and moves relatively independently of the headrest (S3), and is arranged on the seat At least one side of the back frame (1) is connected to the pressure receiving member (20) at the same time, and is a rotating member (30) relatively independently movable relative to the headrest (S3) by a certain impact load. Furthermore, the entire pressure receiving member (20) moves rearward of the seated object by a certain impact load that is heavier than a general seating load.

Description

technical field [0001] The present invention relates to a seat for a vehicle, in particular to a seat for a vehicle capable of cushioning in a rear collision. Background technique [0002] Generally speaking, when the rear of a passenger such as a car is rear-end collided or collided while driving in reverse, that is, in a rear collision, there is a possibility that the head of the seated passenger will be tilted backward rapidly due to inertial force, and the neck will be impacted. question. [0003] For this reason, in order to protect the passenger's head or neck from the impact caused by the rear collision and reduce the impact on the neck for the passenger seat of the current automobile, etc., a seat is installed above the seat back to receive it from the rear. A head restraint for the passenger's head. [0004] However, only the headrest is provided, not only the impact to the body cannot be reduced, but also the distance between the passenger's head and the headrest...
