Abstract: An engagement protrusion (20) extending in the front/back direction of a frame body (13) is provided on one of the opposing surfaces of a notch (16) in the frame body (13) and a fitting member (17) opposite said notch; similarly, an engagement recess (13h) in which the engagement protrusion (20) fits is provided on the other of said surfaces. By means of the moment of the fitting member (17) resulting from the tension of a tension member (14), the engagement protrusion (20) and the engagement recess (13h) are prevented from separating.

Abstract: A stretching structure in which upholstery material can be installed in a frame body, enough deflection allowance of the upholstery material can be ensured. Upholstery material (14) is installed on the surface of a frame body (13) in a closed-loop shape, and is used as the seat or the backrest of a chair. A cross-sectional shape perpendicular to the longitudinal direction of each of the sections of the frame body (13) is provided with an upholstery material receiving section (21) having an engaging groove (20) which is open to the back surface side, and a U-shape section (23) having a recessed groove (22) which is open to the surface side inward more than the engaging groove (20). The upholstery material (14) is wound from the surface of the frame body (13) to the back surface side along the outer peripheral surface, and the edge section is fitted in the engaging groove (20) and tied up, thereby installing the upholstery material (14) in such a manner as to cover the surface of the U-shape section (23).

Abstract: A modular seat frame for a school bus seat includes riser assemblies for supporting the seat fabricated from a moldable material reinforced locally by attachment and reinforcement members.

Abstract: A combined backrest for a chair comprises a left side plastic fastener, a right side plastic fastener and at least one wooden rest board. The left side plastic fastener is fixedly connected to the left side rest staff. The right side plastic fastener is fixedly connected to the right side rest staff, and the left edge part and the right edge pad of the wooden rest board are fixedly connected to the left side plastic fastener and the right side plastic fastener, respectively.

Abstract: The present invention provides a scooter with two chair backs. The scooter includes a main body containing a wheel seat, a pedal and front/rear wheel set; two chair back supports, assembled separately onto both sides on the back of wheel seat of the main body; and two chair backs, incorporated onto at least one chair back support via the connecting frame and transversely arranged at interval. The scooter of the present invention substantially improves the structural functionality and comfort of the chair back of the scooter, and also meets the diversified customer requirements with improved applicability.

Abstract: An auditorium chair comprised essentially of four parts that interconnect creating a frame with a three point stability system. The auditorium chair structure has the following components: fastening with screws, snap tight buttons, or other fasteners, dimensioning in accordance with use in current auditorium chair sizes, and fabrication design enabling efficient shipment while maintaining stability and stacking capability.

Abstract: One aspect is a furniture piece configured for seating. The furniture piece includes first and second contours and a spreader mechanism coupled between the first and second contours. A three-dimensional cover envelope having panels in each of three-dimensions is configured over the first and second contours and the spreader mechanism thereby surrounding the contours and spreader mechanism. The cover envelope is tensioned in each panel creating a simulated cushion.

Abstract: A lightweight, inexpensive folding chair may have a seat with an interference fit support bracket may be provided. The seat may have a lightweight seat member constructed of a lightweight material, such as a blow-molded plastic, that is generally supported by two such support brackets. The support brackets may be affixed to the lightweight seat member by sliding the lightweight seat member into interference engagement with the support brackets. Thus, the lightweight seat member is supported against bending when the chair is in use, in a way that does not concentrate stresses in the lightweight seat member to cause deformation and failure. The support brackets may have an enclosing shape so that the lightweight seat member is unable to move laterally or transversely out of engagement with the support brackets. The support brackets may thus have lips extending into the lightweight seat member to provide the enclosing shape.
