The present invention relates to a spine orienting device for integration into a variety of types of seats, for example, automotive seats or office type seating, in order to properly position the sacrum of the individual using the seat, which in turn will properly pivot the pelvis to assist in maintaining the spine in equilibrium.

An apparatus for a vehicle seat for mobilizing at least one region of a spinal column of a seat occupant sitting in the seat may have a plurality of expandable elements, which may be each filled or fillable with a medium. The expandable elements are drivable sequentially. A method for sequentially driving the apparatus and and a vehicle seat are also provided.

An improved back support designed for use in a seat, to relieve pressure on the user's back. The improved back support includes a first elongated belt segment and a second elongated belt segment. The first elongated belt segment is formed of a first fastening end, and a second attachment end, and the second elongated belt segment is formed of a first fastening end, and a second attachment end. The first elongated belt segment and the second elongated belt segment are adjoined with one or more straps. An individual strap is suspended from the seat to hold the brace in position and when it has been released.

An occupant support may include a seat bottom and a seat back coupled to the seat bottom. In some embodiments, a leg support system is coupled to the seat bottom and configured to support an occupant's leg when in an extended position.

A seat cushion includes a seat cushion base layer which biases two base support parts in directions approaching each other, and has base support part elastic members which are elastically deformed in an up-down direction, thereby causing the seat cushion to have a configuration having a high spring characteristic. In the seat cushion and the seat back, the seat cushion is configured to be set to be larger than the seat back regarding a range of connecting an origin, a maximum displacement point, and a maximum load point, and a ratio of an area of a range including an inward curve to an area of a range including an outward curve in a predetermined load-deflection characteristic.

Transformable seat assembly includes a seat support structure and back support structure connected with an axis of rotation. Actuator assembly includes a cylinder and a piston positioned within the cylinder. The cylinder is secured to one of the back support structure or the seat support structure and the piston is secured to other of the one of the back support structure or the seat support structure. With blocking member in a first position, the piston is permitted to travel between the blocking member and an end of the cylinder spaced apart from the blocking member, such that with the piston traveling to the end of the cylinder, rotation of back support structure is limited from rotating beyond a first reclined position and with blocking member in a second position, back support structure is permitted to rotate into an overlying position relative to the seat support structure.

A transformable seat assembly which includes a seat support structure and a seat connected to the seat support structure with a hinge. The hinge defines an axis of rotation. A back support structure connected to the seat support structure, which extends in an upward direction relative to the seat support structure. A back cushion is secured to the back support structure and a lumbar cushion extends along the back support structure positioned between the back cushion and the seat, wherein the lumbar cushion is releasably secured to one of the back cushion or the back support structure and an end portion of the seat positioned closer to the back support structure with the seat positioned in an occupant support position than the hinge, can rotate in a direction of rotation about the axis of rotation, which includes the upward direction and a direction away from the back support structure.

Back rest to be used in association with a chair or a seat providing an adaptable convex back support for individual adjustment. The back rest comprises a plate shaped body that is bent into a curved shape by use of a tensioning device. The back rest can be used to increase comfort while seated, for example at the office or during travels, or to prevent or relieve back strain and ache as a result of being seated over longer periods or having back problems. The back rest is portable and fits into a backpack or handbag, and can be set up in a conventional chair, for example a seat in an airplane, waiting area, or office chair.

The present invention relates to a spine orienting device for integration into a variety of types of seats, for example, automotive seats or office type seating, in order to properly position the sacrum of the individual using the seat, which in turn will properly pivot the pelvis to assist in maintaining the spine in equilibrium.

A seating assembly includes a seatback. The seatback includes a frame extending about a periphery of the seatback. The seatback defines a thoracic region and a lumbar region. First and second supports extend from a top portion of the frame to a lower portion of the frame. A first flexible mat and a second flexible mat are operably coupled with the first and second supports. The first flexible mat is disposed proximate the thoracic region. The second flexible mat is disposed proximate the lumbar region.
