Abstract

Provided is a vehicle seat that, using a simple configuration that is independent from a headrest, is capable of increasing the amount of sinking (movement) of the entire body of a seated occupant, including the lower back region of the occupant, toward the rear of the vehicle at the time of a rear-end collision, and is capable of effectively reducing the impact on the occupant at the time of a rear-end collision. A vehicle seat S includes a seat back frame 1, a headrest S3, a pressure receiving member 20 that supports the body of the occupant and moves independently from the headrest S3, and pivoting members 30 that are disposed in at least one of side portions of the seat back frame 1, are linked to the pressure receiving member 20, and can move independently from the headrest S3 under a predetermined impact load. The entirety of the pressure receiving member 20 moves toward the rear of the vehicle under a predetermined impact load that is greater than a normal 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...
