Problems solved by technology

[0003] Generally, the seat back of a vehicle seat is constructed by placing a cushioning material on a metal seat back frame and covering it with a skin material. The amount of deformation in this movement is not sufficient to effectively reduce the load on the passenger's body
Also, there is a concern that a huge load is applied to the seat back, thereby causing poor condition of the seat back

Embodiment Construction

[0173] Embodiments of the present invention will be described below with reference to the drawings.

[0174] 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.

[0175] 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.

[0176] In addition, the impact energy at the time of rear collision is the energy due to the huge load generated in the rear collision, the huge collision caused by the passenger coming from behind, the huge collision when reversing, etc., and does not include...

Abstract

Provided is a vehicle seat capable of efficiently absorbing impact energy generated upon a rear end collision in a manner such that the vehicle seat is stably deformed at a specific position with respect to a complex input load generated upon a rear end collision. A vehicle seat includes: frame side portions that are located at the right and left sides of a seat back frame and extend in the up to down direction; and frame extension portions that extend from the frame side portions toward the inside in the right and left direction. A connection portion that connects the frame side portions to the frame extension portions is provided with a deformation portion that is deformed when an impact load is applied thereto. The deformation portion is formed adjacent to other deformation portions having deformation characteristics different from that of the deformation portion.

Description

technical field [0001] The present invention relates to a vehicle seat, in particular to a vehicle seat capable of stably absorbing impact energy in a rear collision. Background technique [0002] Generally, when a vehicle such as an automobile is rear-end hit or receives a large collision while driving in reverse, that is, in a rear collision, the occupant may move backward rapidly due to inertia, and the upper body of the occupant may lean backward. [0003] Generally, the seat back of a vehicle seat is constructed by placing a cushioning material on a metal seat back frame and covering it with a skin material. The amount of deformation in this operation is not sufficient to effectively reduce the load on the passenger's body. Also, there is a concern that a huge load is applied to the seat back, thus causing poor condition of the seat back. [0004] In order to solve such a problem, in Patent Document 1, it is proposed that when a rearward load is applied to the upper p...
