Abstract

The invention relates to a vehicle seat which suppresses deterioration of sitting posture comfort and reduction of massage effect. The vehicle seat is provided with a seat back pad that constitutes apart of a seat back that supports the back of a seated passenger and that has a main portion that constitutes the center portion in the seat width direction and side portions that constitute both sideportions in the seat width direction. The vehicle seat is provided with a skin member having a main portion covering portion that covers a seated passenger-side surface of the main portion, and sideportion covering portions that cover seated passenger-side surfaces of side portions. The vehicle seat is provided with inflation bags which are provided between the main portion and the main portioncovering portion and between the side portions and the side portion covering portions, and which are operated to inflate. The end portion of the main portion covering portion on the outer side in theseat width direction and the end portion of each side portion covering portion on the inner side in the seat width direction are engaged with the seat back pad via a member having greater elasticity at least in part than the end portion of the main portion covering portion on the outer side in the seat width direction and the end portion of each side portion covering portion on the inner side in the seat width direction.

Description

technical field [0001] The present invention relates to a vehicle seat.
