A seat comprising seating and backrest members mounted on a seat support structure. The seating and backrest members are molded plastic foam members lined with an upholstery material and including reinforcement and mounting frames which are foamed into the molded plastic members such that they are integral therewith. The support structure has mounting clips projecting into openings in the molded plastic members and engaging the reinforcement and mounting frames therein. With this arrangement the...

A seat provides a band-like support for the body sides of a user so as to reduce the supporting pressure on the user's lumbar and to hold the user's upper body stably. In this seat, the center of a load to be received in regions symmetrically divided to a vertical central line of the seat are positioned outside of a back region defined by left and right angulus inferior scapulae and by the upper ends of iliac bones. Moreover, the load ratios in the individual regions are not more than 25% in the...

In one embodiment, a seat includes a stiff substantially continuous first sheet suspended at three points on a stiff substantially continuous second sheet. In one embodiment, the first sheet defines a generally flat first wing and a first nose projecting forward from a center of the first wing, the second sheet defines a bow shaped second wing and a second nose projecting forward from a center of the second wing, and the second wing is positioned under the first wing such that left and right sid...

The present invention discloses a seat which is applicable to a vehicle seat, and the seat comprises a seat material whose rear end side is connected to a rear end side of a frame for a sitting portion by way of an elastic member, a plate-like member suppressing deformation of the seat material at a time of sitting, and a fabric-like member suppressing downward sinking of a front portion of the seat material by a tension acting in accordance with sitting.

A seat according to this invention comprises a seat part and a backrest attached to a rear side of the seat part. The seat part comprises a cushion attached to a pair of side supporting frame members connected with each other. The backrest comprises a cushion attached to an inverse U shaped back frame. Each end of the inverse U shaped back frame is connected to each rear end of the side supporting frame members of the seat part. The inverse U shaped back frame comprises side supporting parts tha...

There is provided a seat preventing the baggage or the like from being damaged. A leg rest strain gauge is provided on the bark surface of the leg rest frame on the proximal side. When a baggage is placed in the operating space of the leg rest in the bed position, and the leg rest is moved downward and is abutted against the baggage, the leg rest warps to form a convex on the upper surface in response to a reaction force from the baggage (a force in the direction opposite to the direction of the...

A seat is prepared by molding a synthetic resin foaming material integrally with a frame structure embedded therein. The frame structure includes an upper line frame extending along the upper outer periphery of the seat, a lower line frame connected to the upper line frame and supporting springs for resiliently supporting the upper line frame from below against the load of an occupant.

A seat is made by using a frame fabricated by cold drawing of laminates composed of an inner layer of a non-metallic material sandwiched between two metal foil outer layers.

A seat for a van or the like including auxiliary seat structure pivotally mounted on seat back structure wherein the seat back structure and auxiliary seat structure are selectively movable into and out of a substantially vertical position with the auxiliary seat structure positioned behind the seat back structure and engaged with a floor to which the seat is secured at an angle to prevent pivotal movement of the seat back structure into a horizontal position and a substantially horizontal posit...

The invention relates to a seat having a seat portion that is subdivided by slots to provide resilient individual supporting elements, and wherein the seat portion has a width which exceeds the span of the support for the seat portion. The seat thereby provides a maximum sitting comfort by the superior elasticity of its seat portion, the elasticity extending even into the support for the seat portion.
