Embodiment Construction

[0155] Next, a first embodiment of the present invention will be described with reference to the drawings. In addition, the components, arrangement, 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 be equipped with a seat. Also, the general sitting 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 rear collision refers to the huge load caused by the rear collision, the huge collision caused by the passenger coming from behind, the huge collision when driving in reverse, etc., and does not include the same load range as the load g...

Abstract

A vehicle seat configured in such a manner that the vehicle seat reduces an impact caused by a rear collision and that the structure of the periphery of side frames is simplified. A vehicle seat (S) is provided with: a seat back frame (1) having side sections (15) located at the sides thereof; a pressure receiving member (20) connected to the seat back frame (1) through connection members (21, 22) and supporting the occupant; and an impact reducing member (30) which is disposed on at least one of the side sections (15), is engaged with the connection member (22), and is moved, by a predetermined impact load applied to the pressure receiving member (20), to move the pressure receiving member (20) rearward, the side section (15) having a protrusion section (15e) protruding in the range of movement of the impact reducing member (30). When in contact with the protrusion (15e), the impact reducing member (30) is prevented from moving.

Description

technical field [0001] The present invention relates to a seat for a vehicle, and particularly relates to a seat for a vehicle that reduces the impact of a rear collision and simplifies the peripheral structure of a side frame. Background technique [0002] Generally, when the rear portion of a passenger seat such as a car is rear-ended or is subjected to a large collision while driving in reverse, that is, in a rear collision, the head of the occupant may tilt backward rapidly due to inertia, and the neck may be impacted. question. [0003] For this reason, for the vehicle seats of current automobiles, etc., 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 from the rear. A headrest for the head. [0004] However, even if a headrest is provided, not only the impact load on the body cannot be reduced, but also the distance between t...
