Abstract

A seat back frame and a vehicle seat that effectively reduce impact applied to the neck of an occupant in a rear collision. The seat back frame (1) forming a seat back (S1) has at least a left and right pair of side frames (15), a pressure receiving member (20) placed between the side frames (15), and wires (21, 22) for interconnecting the pressure receiving member (20) and the side frames (15). The wire (22) is connected to the side frames (15) via link members (30) movable relative to the side frames (15). The link members (30) cause the wire (22) to be urged forward from the seat back frame (1) by tension springs (35).

Description

technical field [0001] The present invention relates to a seat back frame and a vehicle seat, and more particularly to a seat back frame and a vehicle seat which reduce the impact on the neck during a rear collision (rear collision). Background technique [0002] At present, when the rear of the car is rear-ended or collided while driving in reverse, that is, in a rear collision, there is a problem that the head of the passenger is rapidly tilted backward due to inertial movement, and the neck is impacted. [0003] For this reason, for vehicle seats such as automobiles, 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, a seat is provided above the seat back to receive the passenger's head from the rear. headrest. [0004] However, even if the headrest is provided, there are cases where the gap between the occupant's head and the headrest cannot be quickly reduced and the impact on the neck cannot...
