Abstract: A pneumatically adjustable bladder system (90) for use in a cushioned seat bottom (24) has one or two rear foam filled bladders (62, 64) for location under the ischial tuberosities of a seated occupant of the seat bottom, and one or more expansion chambers (14, 16) or front foam filled bladders (66, 68) for location under the thighs of the seated occupant. There are air passageways (70, 72, 74, 92) interconnecting the bladders with each other or with an expansion chamber. The system is air tight and the bladders are compressible under the weight of the seated occupant and are expandable when the weight is removed. The compression of a bladder causes air therewith in to be displaced through the air passageways to the expansion chambers or to the other bladders, which then expand.

Abstract: Reinforcement is given in a vehicle seat with such an arrangement that a plurality of recessions and at least one decorative groove are scatteringly formed in each of two spaced-apart protuberant side support portions of the vehicle seat. A foaming is effected to create a foam padding of a predetermined shape of the seat having two spaced-apart protuberant side support portions, such as to define a plurality of first recessions and at least one first decorative groove in each of those two side support portions, after which, a trim cover assembly is pressingly bonded to the thus-formed foaming pad, thereby forcibly inserting and bonding plural points of the trim cover assembly in those first recessions and decorative groove of padding. A resulting seat is therefore provided not only with a highly enlarged area of cured and hardened adhesive layer, but also with an intensified stretched state of trim cover assembly, whereby an increased reinforcement is given to both two side support portions of the seat.

The lateral edges include a webbing or binding made from a non-chaffing material. A method of the making the go cart seat comprises utilizing a two piece mold having flanges at a parting point and mudding the point of separation to provide a smooth rib running along the vertical axis of the top of the back to the bottom of the seat portion.

Abstract: A seat (10) for a chair having a base (11) and ridges (13) which extend transversely of the base (11). The ridges (13) are raised and are engaged by the Ischial Tuberosities of a person sitting on the seat (10) to prevent a person sliding from the seat (10).

Abstract: A pressure reducing cushion with selective pressure point relief features at least two air bladders, and a foam outer layer covering the air bladders. Each air bladder consists of an impervious to air sheet material which surrounds an open celled compressible foam material. Attached to the air bladder is an air flow tube and attached to the air flow tube is a flow control element. When the flow control element is open air from the atmosphere is able to communicate with the interior of the open celled compressible foam material through the air flow tube in combination with the flow control element. The open celled compressible foam material is of such a characteristic that once it is deformed it tends to regain its original shape, thus filling the air bladder with air, if the flow control element is open.
