  • Patent number: 8631695
    Abstract: The disclosed embodiments include a valve stem assembly for a tire pressure monitoring system sensor. The assembly can comprise a valve stem body, and a grommet for purposes of engaging a vehicle wheel. The valve stem body can comprise an attachment end to be attached to a pressure sensor to determine tire air pressure. The valve stem assembly can further comprise a cap that is releasably engaged to the valve stem body which can limit movement of the valve stem assembly relative to the vehicle wheel, the cap having a closed end to cover an air transfer end of the valve stem, and a second open end to overlay the valve stem body and grommet.
    Type: Grant

  • Patent number: 7823479
    Abstract: A vehicle steering column structure includes a movable steering column portion, a tilting mechanism and a telescoping mechanism. The tilting mechanism is configured to selectively adjust an angle of inclination of a tilting part. The telescoping mechanism adjusts the telescopic position of a telescoping part. The telescoping mechanism includes a hand operated release member, an actuation member and a biasing member. The hand operated release member has an actuating end pivotal about first pivot axis between a locking orientation and a releasing orientation. The actuation member has a contact section. The biasing member urges the actuation member to apply an approximately constant return force from the contact section to the actuating end biasing the hand operated release member to return to the locking orientation regardless of the tilt angle of the tilting mechanism.

  • Patent number: 7770487
    Abstract: A vehicle steering column structure includes a fixed steering column portion, a movable steering column portion movably coupled to the fixed steering column portion and a steering column positioning mechanism. The steering column positioning mechanism is operably coupled between the fixed and movable steering column portions for adjusting a relative position therebetween. The steering column positioning mechanism includes a release member and a biasing member. The biasing member biases the release member to a locking orientation such that the biasing force of the biasing member applied to the release member changes with corresponding movement of the release member along a first movement portion of a prescribed movement range and the biasing force of the biasing member is generally constant with movement of the release member along a second movement portion of the prescribed movement range.

  • Publication number: 20060222280
    Abstract: A shaft assembly is provided that has a shaft having a groove disposed in an outer surface of the shaft, a bearing disposed about a portion of the shaft, and a spacer. The spacer has at least a first side and a second side and is positioned at least partially in the groove. The first side and the second side are angled with respect to each other, such that a radially inward portion of the spacer has a narrower width than a radially outward portion of the spacer. At least a portion of the first side of the spacer engages a portion of the groove and at least a portion of the second side of the spacer exerts a longitudinal force towards the bearing.
