A vehicle seat includes a stopping structure that stops forward tilting rotation of a seatback between the seatback and a base on a floor. The stopping structure includes a stopping portion provided on one of the seatback or the base, and a stopper that is provided in a state supported in a cantilevered manner on the other of the seatback or the base, and that extends to a position overlapping with the stopping portion in a seat width direction. The stopping structure is configured to stop the forward tilting rotation of the seatback by abutment of the stopping portion and the stopper. A deformation inhibiting member that minimizes deformation in the seat width direction from the stopper abutting against the stopping portion following forward tilting rotation of the seatback, is provided on the other of the seatback or the base.

The present invention is directed to a tilt-in-space wheelchair that limits the shift of the center of a gravity of a wheelchair occupant during tilting. The wheelchair comprises a main frame adapted to be supported on a surface by wheels, a seat frame for supporting a occupant, and an arc plate for slidably or rollably supporting the seat frame with respect to the main frame. The arc plate defines a first track and a second track that guide the tilting of the seat frame relative to the frame. The first track and second track may have non-constant curvatures. Further, the first track and second track may be arranged non-concentrically on the arc plate and may have different lengths.

A reclining foldable chair includes a support frame and a seat cover secured to the support frame. The support frame is configured to transition between a storage and use position and includes a first and second upright, a seat bottom support, a collapsible cross-brace, a seat back rest, and a reclining assembly configured to allow the chair to transition between upright and reclined positions. The reclining assembly includes a recline limiter and a pivoting link latch. The pivoting link latch includes a pivoting link and a moving link, wherein an overall length between opposite ends of the pivoting link and moving link is adjustable in order to transition the reclining foldable chair between the upright and reclined positions.

A collapsible stadium seat with a seat member that defines a base plane, and seat membrane support members. A seat membrane is coupled to and spans the space between the seat membrane support members to define a user seating surface. The seat membrane is angled backward such that its front portion is farther from the base plane than is its back portion. There is also a cantilevered back that is pivotably coupled to the seat member and includes first and second spaced back support members. A back membrane is coupled to the support members. The support members are angled or curved to define a lumbar support region. There are back adjustment mechanisms that can be locked and unlocked and allow the back to pivot, to establish a comfortable use position.
