  • Patent number: 8578813
    Abstract: In a parking brake system, a locking tooth of a ratchet plate includes a first area for contacting and retaining a locking claw of a ratchet pawl in an equilibrium state when a parking brake lever is pulled up; and a second area in which the locking claw remains in a state of halfway engagement of tooth tips when a pressing force of a release rod is released. When the locking claw comes into contact with a portion closer to a tip of the locking tooth beyond the first area, a line of force is maintained due to the pressing force of the release rod. The system is configured such that even if an occupant erroneously pulls up the parking brake lever while the release rod is pressed, it is possible to reliably prevent halfway engagement of tooth tips in a ratchet mechanism.

  • Patent number: 5775165
    Abstract: A transmission shift control has a detent mechanism to provide a shift effort so that the operator has a sense of feel during shifting between ranges. During a manual shift between reverse and park, the shift effort or "detent feel" is normally higher than the effort occurring during manual shifts between other ranges. The detent mechanism providing the "detent feel" is comprised of a spring-biased roller in a notched detent plate comprised of rises and valleys. The spring urges the roller against the notched surface on the plate. The ramps or rises provide increased shift effort during movement of the plate from range to another. In each range, the spring-biased roller is disposed in the appropriate valley. A channel is formed in the plate to provide a path for the roller, such that the park to reverse shift effort is less than the reverse to park effort.

  • Patent number: 5758547
    Abstract: A foot-operated parking brake actuator applies a parking brake by moving an input pedal lever between a brake-released position and a plurality of brake-applied positions to operate a cable to apply and release a vehicle parking brake. A mounting bracket pivotally mounts the pedal for pivotal movement about a first pivot. A sector gear is secured to the bracket with its center on the first pivot, and mounts a cable take-up reel. The cable is attached to the reel which is pivotally mounted on the pedal lever about a second pivot. A pinion is secured to the reel for engagement with the sector gear upon pedal lever movement to brake-apply positions to wind the cable on the reel. Cable winding occurs at a sequence of variable input/output force ratios of input pedal lever force to output cable force or load to apply the parking brake, the ratio varying with pedal movement because of the complex movement of the reel.

  • Patent number: 4976167
    Abstract: A tilt telescope steering column comprises a bracket pivotably supporting a housing between first and second pivot limits. The first and second pivot limits may be changed. A pair of screws attach the housing to the bracket and clearance between the screws and the housing is taken up. A tubular member is located within the housing and is axially movable relative to the housing. Axially spaced bearings engage the housing and the tubular member to take up clearance therebetween. A tilt blocking mechanism includes a lock member carried by the housing and movable to a position blocking relative pivotal movement between the housing and the bracket. The lock member is moved against a surface of the housing when the lock member is in its blocking position to take up clearance between the lock member and the housing. A telescope blocking mechanism includes a lock pin which is movable to a position blocking relative axial movement of the tubular member and the housing.

  • Patent number: 4793204
    Abstract: A tilt and telescope steering column is disclosed in which a single control member operates the lock and release of a tilt lock mechanism and a telescope lock mechanism. Both lock mechanisms include pivotally mounted pawls having teeth which interfit with teeth on an associated housing assembly to lock the column in its adjusted position. The pawls are movable in opposite directions from their respective locked positions to release positions in which adjustment of the steering column is permitted. A control member is mounted for movement in two directions and operates in one direction to release one lock system and in the opposite direction to release the other lock system. Spring means normally maintain the locking pawls in their locked position and also maintain the control member in its neutral position. In one embodiment, a single spring functions to normally maintain both lock mechanisms in their locked position and also normally maintains the control member in its neutral position.

  • Patent number: 4750379
    Abstract: A tilt steering apparatus for vehicles includes a fixed bracket and a rotational bracket rotatably mounted on the fixed bracket and having a ratchet fixed on a side thereof. A pawl, pivotally mounted on the fixed bracket, engages the ratchet when the rotational bracket is in an upward position and in a downward driving position. Memory means memorizes a selected engagement relationship between the pawl and ratchet when the pawl and ratchet are engaged and the rotational bracket is in a downward position. When the rotational bracket is subsequently being rotated to the downward position, intermediate means maintain the ratchet and pawl in a disengaged state until the rotational bracket is in the downward driving position.

  • Patent number: 4643043
    Abstract: A vehicle hand brake lever assembly for actuating the vehicle parking brake. The lever assembly includes an axially slidable plunger mounted on a support and having one end connected with a brake actuating member. The plunger and the support have a ratchet mechanism for holding the plunger at the brake applying position. The ratchet mechanism can be released by rotating the plunger about its longitudinal axis. A handle assembly is provided at the other end of the plunger and comprises a handle having a handle shaft. A sleeve fitted to a cylindrical guide member is secured to one of the sleeve and the handle shaft, and a lock member to the other. The lock member is axially slidably received in the guide member and provided with a cam profile for cooperation with a cam profile provided on the sleeve. The lock member is spring biased toward the sleeve so that the cam profiles are normally engaged with each other to thereby maintain the handle shaft at a predetermined relationship with respect to the plunger.
