  • Patent number: 11407440
    Abstract: A steering column assembly includes a first shaft, a second shaft, and a clip. The first shaft has a first yoke disposed at an end thereof. The second shaft has a second yoke disposed at an end thereof. The second yoke is connected to the first yoke such that rotation of the first shaft is configured to rotate the second shaft and such that the second shaft is rotatable relative to the first shaft. The clip is removably connected to one of the first shaft and the second shaft. The clip limits rotation of the second shaft relative to the first shaft prior to installation of the steering column assembly in a vehicle.

  • Patent number: 10801390
    Abstract: A vehicle exhaust system includes a vehicle body structure, an exhaust system, a rear bumper assembly, an exhaust finisher and a boot. The exhaust assembly is supported to an underside of the vehicle body structure. The rear bumper assembly is also supported to the vehicle body structure. The exhaust finisher is non-movably attached to one of the vehicle body structure and the rear bumper assembly. The exhaust finisher extends at least part way through an opening of the rear bumper assembly. The boot has a first end, a second end, and a flexible portion. The first end is attached to a rear end of the exhaust assembly. The second end is attached to a forward end of the exhaust finisher and the flexible portion extends from the trout end to the second end. The flexible portion is elastically deformable in response to thermal expansion and contraction of the exhaust assembly.

  • 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.
