The ventilated seat cushion for children has a favorable effect of ventilation and cooling, improving the comfort of children when sitting in a trolley or a car safety seat; the ventilated seat cushion for children can not only be used for a children trolley, but can also be used for a car safety seat for children; and providing seat belt perforation opening (B) can improve the safety of children riding in cars.

The purpose of the present invention is to provide a seat that makes it possible to easily connect the end of a surface cover when assembling the surface cover and to achieve a secure connection. To this end, a seat (1) is provided with inclined piles (70, 80) on the end of the surface cover (4) and at a location that faces the end of the surface cover (4) on a cushion member (2) that forms a seat section, the inclined pile (80) of the cushion member (2) is inclined in a direction that is the opposite of the direction in which a load resulting from a seated person occurs, and the inclined pile (70) of the end of the surface cover (4) is inclined in the direction in which the load resulting from a seated person occurs.

A net-like structure has a three-dimensional random loop bonded structure constituted of a thermoplastic elastomer continuous linear body having a fiber size of greater than or equal to 0.1 mm and less than or equal to 3.0 mm. The net-like structure has, in the thickness direction, a solid-section fiber main region mainly including solid-section fibers, a hollow-section fiber main region mainly including hollow-section fibers, and a mixed region including solid-section fibers and hollow-section fibers in a mixed state, located between the solid-section fiber main region and the hollow-section fiber main region. Both solid-section fiber main region-side residual strain of the net-like structure and hollow-section fiber main region-side residual strain of the net-like structure are less than or equal to 20%, and the difference between the solid-section fiber main region-side residual strain and the hollow-section fiber main region-side residual strain is less than or equal to 10 points.

An occupant support device (OSD) for a seat, comprises a flexible membrane having a first end and a second end. The flexible membrane is coupleable to a seat proximate the first end and the second end of the flexible membrane. The OSD further comprises at least one stiffening member for stiffening the flexible membrane. The at least one stiffening member is positionable so that the flexible membrane is generally stiffer in a longitudinal direction than in a transverse direction. A seat comprising the OSD, an array of seats comprising the OSD and an aircraft comprising the OSD are also provided.

The present invention provides a network structure having excellent repeated compression durability, a low repeated compression residual strain and a high hardness retention after repeated compression. A network structure made of a three-dimensional random loop bonded structure obtained by forming random loops with curling treatment of a continuous linear structure including at least one thermoplastic elastic resin selected from the group consisting of a polyolefin-based thermoplastic elastomer, an ethylene-vinyl acetate copolymer, a polyurethane-based thermoplastic elastomer and a polyamide-based thermoplastic elastomer, the continuous linear structure having a fineness of not less than 100 dtex and not more than 60000 dtex, and by making each loop mutually contact in a molten state, wherein The network structure has an apparent density of 0.005 g/cm.sup.3 to 0.20 g/cm.sup.3, a 50%-constant displacement repeated compression residual strain of not more than 15%, and a 50%-compression hardness retention after 50%-constant displacement repeated compression of not less than 85%.

Provided is a vehicle including the following: a vehicle body having side walls on both sides in a width direction that is perpendicular to the direction of travel, and having an expanded portion between the upper end and the lower end of the side wall, the expanded portion being expanded further outward in the width direction than the upper end and the lower end; and a seat provided in the vehicle body and having a seatback along the side wall and a seat surface that extends inward in the width direction of the vehicle body from the seatback, the portion of the rear surface of the seatback that faces the side wall and that protrudes the farthest towards the side wall being disposed in a position facing the expanded portion of an in-vehicle-side lateral surface of the side wall.

[Problem] To provide a cushion pad that allows reducing the oppressive feeling in a thigh and the sinking of buttocks and improving the texture and the fit feeling. [Solution] In a portion positioned underneath a hip point of a seated person, an under-buttock portion is set to have a smaller force S.sub.25 during compression to 25% in a second portion including a seating surface than S.sub.25 of the first portion positioned on a bottom surface side. The thigh supporting portion is set to have smaller S.sub.25 of a portion including the seating surface than S.sub.25 of the first portion. This allows reducing the oppressive feeling in the thigh and the sinking of the buttocks and improving the texture and the fit feeling.
