  • Patent number: 6766712
    Abstract: A steering column (10) includes a mounting bracket (66) connecting the steering column (10) to a vehicle frame. A support (24), through which a steering column member (12) extends, is connected with the mounting bracket (66). The support (24) supports the steering column member (12) for rotation about and is movable relative to the mounting bracket. A locking mechanism (130) locks the support (24) in any one of a plurality of positions relative to the mounting bracket (66). The locking mechanism (130) has a locking lever (132) with first and second ends (171 and 136). A spring (194) applies a force to the first end (171) of the lever (132) to urge the second end (136) of the lever to clamp the support (24) to the mounting bracket (66). The first end (171) of the lever (132) moves against the force applied by the spring (194) to permit movement of the support (24) relative to the mounting bracket (66).

  • Patent number: 6666478
    Abstract: A steering column (10) includes a support (24) through which a steering column member (12) extends. An over-center locking mechanism (130) locks the support (24) in any one of a plurality of positions relative to a mounting bracket (66). The locking mechanism (130) has a locking member (132) that has a first position in which a portion (46) of the support (24) and a portion (72) of the mounting bracket (66) are urged toward each other to prevent movement of the support (24) relative to the mounting bracket (66). The locking member (132) has a second position in which the support (24) and the mounting bracket (66) are movable relative to each other. The locking mechanism (130) applies a first force to the locking member (132) to move the locking member from the first position to the second position and applies a second force to the locking member to move the locking member from the second position to the first position.

  • Patent number: 6662674
    Abstract: A steering column (10, 210) includes a support (24, 224) which supports a steering column member for rotation about a longitudinal axis (26, 226). A mounting bracket (50, 266) connects the steering column (10, 210) to a vehicle frame. A pair of arms (66, 68 and 276, 278) interconnects the support (24, 224) and the mounting bracket (50, 266). Each of the arms (66, 68 and 276, 278) has an end (72, 78 and 296, 304) pivotally connected with the mounting bracket (50, 266) and an end (88, 98 and 310, 318) pivotally connected with the support (24, 224). A locking mechanism (108, 330) locks the arms (66, 68 and 276, 278) relative to the mounting bracket (50, 266) and locks the support (24, 224) relative to the arms. The locking mechanism (108, 330) includes a locking shaft (110, 340) extending through the mounting bracket (50, 266), one of the arms (66, 68 and 276, 278), and into the support (24, 224).

  • Publication number: 20030094060
    Abstract: A steering column (10) includes a steering column member (12) connectable with a steering wheel and rotatable to turn steerable vehicle wheels. A mounting bracket (66) connects the steering column (10) to a vehicle frame. A support (24), through which the steering column member (12) extends, is connected with the mounting bracket 66. The support (24) supports the steering column member (12) for rotation about a longitudinal axis (26) of the steering column member (12) and is movable relative to the mounting bracket. A locking mechanism (130) locks the support (24) in any one of a plurality of positions relative to the mounting bracket (66). The locking mechanism (130) has a locking lever (132) with first and second ends (171 and 136). A spring (194) applies a force to the first end (171) of the lever (132) to urge the second end (136) of the lever to clamp the support (24) to the mounting bracket (66).
