摘要:
A shape memory alloy (SMA) system suitable for use in any number of environments, including but not limited to latching and unlatching vehicle seat tracks. The system including any number of configurations to support any number of operations, including but not limited to push-push, pull-pull, push-pull, and pull-push operations.

A vehicle seat assembly includes a seating surface, wherein the seating surface defines a plurality of temperature controlled zones. At least one electrically actuated heating/cooling source provides one of heating and cooling to the plurality of zones. A controller individually controls electrical power supplied from the source to each zone and is operative to reduce power consumption in one zone relative to another zone in accordance with a predetermined profile designed to limit the overall power consumption of the assembly.
摘要:
A seat heating and occupant sensing assembly including a mat having a plurality of heat sources disposed therein. A power supply supplies power to the heat sources. The assembly further includes a controller in communication with a signal generator. The signal generator provides electric signals to the heat sources to form an electric field. The controller monitors one of the signals and electric field for recognizable characteristics for determining the presence of an occupant on the seat.

A vehicle seat assembly includes a seat back that is pivotally connected to a seat bottom, a lock mechanism that is configured to inhibit the seat back from pivoting when locked and to permit the seat back to pivot when unlocked, and a release and drive mechanism. The release and drive mechanism includes a mounting member, a drive gear that is rotatable with respect to the mounting member and that is connected to the lock mechanism, and a motor that is connected to the drive gear. The drive gear is rotationally limited to a defined angular range. The motor rotates the drive gear through the defined angular range which moves the lock mechanism to an unlocked state and thereafter causes the seat back to pivot.
摘要:
A linear motion actuator is disclosed in which an actuator shaft is held in a ready position by a latching ring. A spring is attached to the actuator shaft to exert a biasing force on the actuator shaft biasing it toward its actuated position. The latching ring receives one end of the actuator shaft and has locking elements that hold the actuator shaft in the ready position. A latching ring is rotated to selectively release the locking element. A shape memory alloy link extends partially around the latching ring and is secured to the latching ring. The link is shortened when current is applied to the link causing the link to rotate and release the locking element.
