Abstract

A vehicle seat is such that a seating surface is formed by a plurality of pad block portions, each of which has a convex shape due to a pleat structure, that are fit together, with a sectional shape in a width direction of the seating surface being a concave shape. Even at a location of the seating surface formed in the concave shape that is affected by a difference in body shape of a seated person, a shape of the location is formed in a shape following the body shape of the seated person.

Claims

1. A vehicle seat comprising:

a plurality of pad block portions defining a generally concave seating surface configured to accommodate a seated person, wherein

each of the plurality of pad block portions has a convex shape,

the plurality of pad block portions are fitted together so that the seating surface is defined as a pleated structure,

an interference fit portion is provided on both end sides of the seating surface to accommodate different body shapes of the seated person,

the interference fit portion includes a side pad block portion of the plurality of pad block portions and a top pad block portion of the plurality of pad block portions,

a slab pad member is provided on each of the side pad block portion and the top pad block portion and the slab pad member is softer than a base pad member on which the plurality of pad block portions are provided, and

the slab pad member includes an outer side high resilience slab pad member and an inner side low resilience slab pad member arranged such that the outer side high resilience slab pad member overlaps the inner side low resilience slab pad member in a seating surface direction.

2. The vehicle seat according to claim 1, wherein the inner side low resilience slab pad member extends partially across a seating side surface portion of the side pad block portion and a seating side surface portion of the top pad block portion, and the outer side high resilience slab pad member extends entirely across the seating side surface portion of the side pad block portion and the seating side surface portion of the top pad block portion.
