A vehicle seat can be configured to provide support to a vehicle occupant in conditions when lateral acceleration is experienced. Shape memory material members can be operatively positioned with respect to a seat portion of the vehicle seat. The shape memory material members can be selectively activated by an activation input. When activated, the shape memory material members can engage a seat pan so as to cause the seat pan to tilt in a respective lateral direction. As a result, a seat cushion supported by the seat pan can also tilt in the respective lateral direction. The seat cushion can be tilted in a lateral direction that is opposite to the direction of the lateral acceleration. Thus, the effects of lateral acceleration felt by a seat occupant can be reduced. The shape memory material members can be selectively activated based on vehicle speed, steering angle, and/or lateral acceleration.

A lordosis support for seat back rests, includes a support plate (10) held between two frame legs (14) of the back rest by tension members (12) and having on each side at least one point of attack (22) for the respective tension member (12), and an adjusting device (24) for adjusting the tension force of the tension members (12), wherein the distance between the two points of attack (22) is adjustable and the adjusting device (24) is configured to change this distance.

An adjustable back support for a mobility device includes a first adjustable back support assembly including a first support member and a second support member, and a second adjustable back support assembly. The first support member is moveably connected to the second adjustable back support assembly, the first support member being configured to pivot relative to the second adjustable back support assembly relative to a first axis of rotation, and the second support member is moveably connected to the first support member, the second support member being configured to pivot relative to the first support member relative to a second axis of rotation that is not parallel to the first axis of rotation.

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 adjustable back support for a mobility device includes a first adjustable back support assembly including a first support member and a second support member, and a second adjustable back support assembly. The first support member is moveably connected to the second adjustable back support assembly, the first support member being configured to pivot relative to the second adjustable back support assembly relative to a first axis of rotation, and the second support member is moveably connected to the first support member, the second support member being configured to pivot relative to the first support member relative to a second axis of rotation that is not parallel to the first axis of rotation.

An adjustable chair support system includes a first seat back support member spaced from a second seat back support member, and a seat back tensioning assembly extending between the first and second seat back support members, the seat back tensioning assembly includes a carrier, an adjustable tension member coupled to the carrier, and a cable, wherein the cable extends between the first and second seat back support members a plurality of times, and wherein the adjustable tension member is configured to adjust a tension of the cable.

A seating assembly includes a frame that has an upper portion that defines an attachment aperture and a lower portion. A bracket is coupled to the lower portion. A cable has a first end and a second end that is coupled to the bracket. The cable is operable between a support position and a compressed position. A guide-sleeve is operably coupled with the cable and is disposed within the attachment aperture of the upper portion of the frame. The guide-sleeve includes retention tabs that are operably coupled to the upper portion.

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.

An office system including a first component and a second component moveable relative to the first component. A distance and/or force multiplier is disposed between and coupled to the first and second components. The distance and/or force multiplier includes a shape memory material, wherein the shape memory material is contractible between at least a non-energized state and an energized state in response to an application of energy. The distance and/or force multiplier moves the second component relative to the first component when the shape memory material is contracted to the energized state.

A vehicle seating assembly includes a frame and an articulating flexmat assembly operably coupled with the frame. The articulating flexmat assembly includes an upper flexmat extending from a first side of the frame to a second side of the frame and a lower flexmat extending from the first side of the frame to the second side of the frame. The upper flexmat includes an upper static portion and an upper dynamic portion disposed above the upper static portion and adjustable by upper linear actuators that draw the upper dynamic portion toward the upper static portion to arc the upper flexmat outward. The lower flexmat includes a lower static portion adjacent to the upper static portion and a lower dynamic portion disposed below the lower static portion and adjustable by lower linear actuators that draw the lower dynamic portion toward the lower static portion to arc the lower flexmat outward.
