Vehicle seat
(57) Abstract

A vehicle seat has a first member and a second member bonded to each other with an adhesive agent is provided with a projecting portion that projects from an adhering surface of the first member toward the second member with one end to the other end in a protruding direction of the projecting parts held on the inner side of an outer edge of the adhering surface. An adhesive agent layer formed by the adhesive agent interposed between the first member and the second member surrounds the projecting portion while in contact with the outer circumferential surface of the projecting portion.

Description

Disclosed herein is a vehicle seat, and in particular, a vehicle seat that has a first member and a second member bonded to each other with an adhesive agent.

When a vehicle seat is assembled, there are cases where components of this vehicle seat are bonded to each other with an adhesive agent. Especially when seat components are resin molded products that cannot be bonded to each other with welding, a bonding method using an adhesive agent is employed.

In some configurations in which components are bonded to each other with an adhesive agent, a projecting portion is formed to protrude from the adhering surface of a component (i.e., the surface of a component which faces another component) toward another component (e.g., refer to Japanese Patent Document No. 2008-273053 A (“the '053 Document”)).

To give a more specific description of the bonding method described in the '053 Document, when components are placed close to each other at an adhering step, a projecting portion of a component is abutted against an adhesive agent layer coated on the other component in the direction from a tip end thereof. Then, the layered adhesive agent is pressed and widened by the projecting portion, thereby spreading out over a wide area. As a result, this enables the components to adhere well to each other while suppressing air from being trapped in the adhesive agent layer, or so-called voids from being generated therein.
