Problems solved by technology

[0004] However, even if a headrest is provided, not only the impact load on the body cannot be reduced, but also the distance between the passenger's head and the headrest cannot be rapidly reduced during a rear collision, and it is difficult to sufficiently reduce the impact on the neck.

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

Provided is a vehicle seat by which an impact of rear end collision is reduced and of which peripheral structure of a side frame is simplified. A vehicle seat includes: a seat back frame which includes side portions positioned at the sides thereof, a pressure receiving member which is jointed to the seat back frame through joint members and supports an occupant, and an impact reduction member which is disposed on at least one of the side portions to engage with the joint member and to move by a predetermined amount of impact load applied to the pressure receiving member so that the pressure receiving member is caused to move rearward; in which the side portion includes a convex portion protruding in the movement range of the impact reduction member, and the impact reduction member abuts against the convex portion so that the movement of the impact reduction member is prevented.

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 vehicle such as a vehicle is rear-ended or a large collision is received 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 inertia, and the neck is impacted. [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 betwe...
