Appl. No.:

10/904203

Inventors:

Mark R. Keyser - Lake Orion MI, US
Michele R. Palomba - Romeo MI, US

Assignee:

Lear Corporation - Southfield MI

International Classification:

B60N 2/02
B60N 2/04

US Classification:

29737812, 296 6509

Abstract:

A remote release actuating system for a seat assembly in a vehicle. Conventionally, the system includes a seatback that is removable through an arcuate range. The seatback is moveable between a design position (tilted upward and rearwardly in which it may support a passenger), and a full fold flat position. Seatback latches secure the seatback in the effective position. A seat cushion supports the seatback. The seat cushion has a rearward portion that cooperates with the seatback. The rearward portion also releasably engages floor latches. The seat cushion has a forward portion that is pivotally attached to the vehicle floor. The seat cushion and seatback tumble forwardly when (a) the seat cushion is disengaged from the floor latches ; (b) the seatback lies in the full forward flat position; and (c) the floor latches are disengaged. The tumble forward position facilitates occupant ingress and egress in relation to the vehicle and provides access to luggage and storage areas. In operative communication with the seatback and floor latches , there is provided a release system for releasing these latches that is located remotely from the seatback and the seat cushion.

International Classification:

H01H 71/18

US Classification:

310306, 60527, 297330

Abstract:

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.

International Classification:

B60N 2/22
B60N 2/235

US Classification:

297362, 29736211

Abstract:

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.

International Classification:

B60N 2/02

US Classification:

29736211, 29737814

Abstract:

A seat support system for supporting a seat in a manner that ameliorates or eliminates load applied to a driving mechanism. The system may be configured to support a seat back when the seat back in pivoted upwardly and downwardly relative to a seat bottom. The support system may create a load-bearing link between a non-driven component on the seat back and an anchor.

US Classification:

297341, 296 6518

Abstract:

A seat is provided including a seat body assembly having a seat bottom that is configured for movement between a rear position and a forward position, and a seat back connected to the seat bottom. The seat back may be configured to pivot between a first position and a second position. The seat bottom may be moveable to the forward position when the seat back pivots to the second position. The seat further includes an electric actuator assembly associated with the seat body assembly that permits the seat back to pivot to the second position when the electric actuator assembly is actuated.

International Classification:

B60R 2236

US Classification:

280806

Abstract:

A safety belt tensioner is provided for pulling a buckle part to tighten a safety belt system about an occupant. The tensioner includes a flexible member or cable having a first loop connected to the buckle part which pulls the buckle part when it is shortened, as by actuation of a power operated device such as a piston-cylinder device. To shorten the piston stroke while achieving the necessary displacement of the buckle part, the flexible member is provided with a second loop connected to the piston about a turning member thereof with one end of an anchored half of the second loop secured to a stationary part of the pretensioner, and the other loop half extending from the cylinder and connected to the portion of the flexible cable member for the buckle part. This provides about a 1:1 ratio between the length of piston travel and downward travel of the buckle part to minimize the piston travel to allow the length of the cylinder to be shorter for providing a more compact pretensioner. In a preferred form, the piston has a rotatable bearing member about which the second loop extends which reduces friction on the cable when the piston is fired.
