A fastener is used to connect a first link to a second link in a vehicle seat assembly. The fastener has a head portion and a body portion extending outwardly from the head portion and defining an external diameter. The body portion is generally cylindrical and has a central bore with an internal diameter that is less than the external diameter. The method for connecting the first link to the second link with the fastener includes the steps of inserting the central body portion through aligned apertures in the links to form a subassembly and holding the subassembly fixed while a tooling member applies a linear load to the distal end of the body portion. The tooling member is inserted into the central bore and deforms the body portion for engagement with the first and second links to allow relative rotational movement between the links while eliminating relative linear movement therebetween.

A vehicle seat assembly includes a seat back that is supported with respect to a seat bottom. The seat bottom is supported on a track assembly that includes a seat adjuster for controlling movement of the seat back and bottom. The seat adjuster can move the seat in horizontal and/or vertical directions and can also be used to adjust the tilt of the seat. An electric motor is used to drive the seat adjuster. The motor supports a first connector and the seat adjuster supports a second connector. A flexible shaft is used to interconnect the first and second connectors to transmit power from the motor to the adjuster. The shaft has a first end and a second end with each of the ends defined by a helical body portion. The first connector and the first end are mated to interconnect the motor and the shaft and the second connector and the second end are mated to interconnect the seat adjuster and the shaft. The helical body portion of the first and second ends is twisted with respect to the first and second connectors such that there is a slight interference fit between the ends and the connectors. The use of the helical body to create the interference fit allows for easy assembly of the shaft to the motor and seat adjuster and is quiet in operation.

Flex cable drive for seat adjuster assembly

A support structure for a vehicle seat assembly which allows the seat position to be adjusted forwardly or rearwardly with respect to the vehicle. The seat support structure is mounted to a vehicle structure and includes a first track, a second track, a torque tube and a brace member supported for movement relative to the first track with the seat bottom being supported on the second track for movement relative to the first track. A restraint bracket which is attached to the seat belt is adjacent the torque tube and second track without the necessity of fasteners. The restraint bracket mounting allows a force to be transfered to the associated torque tube, first track, and second track. The present invention further provides a method of seat assembly in which the torque tube is maintained under compression and the brace member under tension to provide a rigid, integral seat support structure.

A linkage assembly is used to vertically adjust the position of a seat. The linkage assembly includes a first link that is connected to a second link without the use of fasteners. The first link has a first mounting portion and the second link has a second mounting portion. The first mounting portion is deformed into engagement with the second mounting portion to rotatably connect the first link to the second link. In one embodiment, the first mounting portion is an extrusion that extends through an aperture in the second link. An end of the extrusion is deformed into engagement with the second link to form a lip to lock the first link to the second link and allow relative rotational movement between the first and second links while eliminating relative linear movement therebetween. In an alternative embodiment, portions of the first and second links are deformed into locking engagement.

Simplified linkage assembly

The present invention relates generally to a fastener used for connecting a first link member to a second link member in a linkage assembly. The second link member includes a pair of aligned apertures and a slot located transversely between the apertures. The first link member includes an aperture at a first end that is designed to be received in the slot located in the second link member. The fastener has a centering post at a distal end and a head portion at a proximal end with a self-tapping portion located between the head portion and the centering post. The aperture in the first link member is aligned with the apertures in the second link member and the fastener is inserted through the apertures until the self-tapping portion contacts the first link member. Thereafter, rotation of the fastener in a first direction taps the self-tapping portion of the fastener through the aperture in the first link member. The fastener is rotated until the first link member is flush against the head portion of the fastener. Thus, the fastener rotatably secures the first link member to the second link member and prevents lateral free play movement between the fastener and the second link member, and between the first link member and the second link member.

A ring seal for protecting a designated area from ambient contamination is alternately placeable into its sealing and non-sealing positions. The ring seal permits a limited travel between the sealable surfaces without compromising the seal integrity. The ring seal facilitates an interference-free installation and selective maintenance of the sealable parts.
