Problems solved by technology

[0003] However, depending on the shape of the cushioning material and the weight of the occupant, the compression deformation of the cushioning material may not be sufficient, so that the body pressure may not be sufficiently distributed, or the subsidence may be insufficient, and the area around the ischial tuberosity may be strongly compressed. numbness, pain
As a result, the seated person feels discomfort and in severe cases even pain, and prolonged sitting becomes painful

Abstract

The invention provides a cushion body for seating, which can give good seating feeling to a plurality of non-specific seated persons with various body shapes and can be seated more comfortably. A cushion body (1) for seating is provided with: a base part (2) having a seating surface (S1) which supports the buttocks of a seated person in a seated posture from below and which is configured from a curved surface that is curved in a concave shape; and a pair of side support pieces (3) having a side support surface (S2) comprising a curved surface continuously curved from the seating surface (S1) of the base part (2), the pair of side support pieces (3) extending from the side parts of the base part (2) so as to be capable of being bent and deformed by a load applied to the side support surface (S2), and supporting the left and right side parts of the buttocks of the seated person in the seated position.

Description

technical field [0001] The present invention relates to a cushioning body for seating to enable more comfortable seating. Background technique [0002] Currently, there is known a flat-shaped seat cushion that is easily compressed and deformed by the weight of a seated person. The flat-shaped seat cushion is made of a soft cushioning material such as soft polyurethane foam or fiber-based cushioning material. When a seat occupant sits on such a seat cushion, the seat cushion sinks due to the body weight, forming a concave portion similar to the shape of the buttocks, thereby distributing the body pressure of the seat occupant. [0003] However, depending on the shape of the cushioning material and the weight of the occupant, the compression deformation of the cushioning material may not be sufficient, so that the body pressure may not be sufficiently distributed, or the subsidence may be insufficient, and the area around the ischial tuberosity may be strongly compressed. And...
