A device for allowing a user to ride in a vehicle is provided. The device may include: a seat unit having one or more portions of foam materials; one or more accessory units to support the functionality of the seat unit; and one or more seat configurations to attach the seat unit to the vehicle.

A seating arrangement includes a support shell including a seat portion and a chair back portion each configured to support a seated user, the chair seat portion having a front region and a rear region and the chair back portion having an upper region and a lower region, where the rear region of the seat portion is coupled to the lower region of the chair back portion, a control member including a substantially flexible front support and an attachment point, where the front support engages the support shell in the front region of the seat portion and the control member engages the back portion, and a substantially rigid second support attached to the control member at the attachment point, wherein the control member is an integral, one-piece component including multiple flex regions configured to allow the support shell to move between an upright and reclined position.

A folding chair may include a frame that is configured to transition the folding chair between use and storage positions. A seat base may be pivotally coupled thereto at a first particular length from a front end and a receiving portion may be disposed in an upper surface. The receiving portion may include left and right lateral edges, front and rear longitudinal edges, and a depth. The padding material may be disposed in the receiving portion and may have a lateral dimension related to a distance between the front and the rear longitudinal edges, a longitudinal dimension related to a distance between the front and the rear longitudinal edges, and a thickness related to the depth. The padding layer may cover a majority of a top surface of the padding material and of the upper surface. The cover may retain the padding material and the padding layer relative to the seat base.

A chair (10) has a composite structure (14) attached to a frame (12). The composite structure includes a plastic plate (16) having an edge (22), and a metal plate (18) having a peripheral crimp (21) including a gap (20), with the edge of the plastic plate inserted into the gap and with the peripheral crimp clamped onto the edge of the plastic plate, to attach the plastic plate onto the metal plate. The composite structure provides a seating surface of the chair. The composite structure maximizes the advantages of both the plastic plate and the metal plate, with each plate compensating for the disadvantages of the other.

A seat shell includes a one-piece shaped wooden shell which has a seat part and a backrest part and which in its transition region has a bent portion bent along a bending axis. The shaped wooden shell has a veneer structure including at least nine wood layers glued on top of each other. The wood layers include a top layer at each of the front and rear of the shaped wooden shell, respectively, the top layer made of a wood layer is arranged in the longitudinal direction. The wood layers also include between the top layers a number of middle and outer wood layers arranged in the longitudinal or transverse direction. The shaped wooden shell is upholstered, and has a transversely extending cutout defined by bars at the edge in the transition region and/or the backrest part.

A blow-molded plastic structure has a hollow interior portion formed during a blow-molding process, and includes first and second outer portions that are spaced apart from each other, with the hollow interior portion disposed there between. The structure includes a pattern of structural stiffening features that are integrally formed in the second outer portion. The pattern of structural stiffening features includes a plurality of tripodal depressions disposed in rows and columns and a plurality of convex regions disposed in rows and columns between the plurality of tripodal depressions. Each convex region has a maximum height between the first and second outer portions. Each of the tripodal depressions extends into the hollow interior portion, includes three indentations disposed adjacent the first outer portion, and includes an island spaced away from the first outer portion. The island has three sides, each of which is disposed adjacent one of the three indentations.
