  • Patent number: 11697447
    Abstract: A tilt assembly (30) for a steering column assembly (10) including a pair of downwardly disposed plates each having a slot (36); an elongated member adapted to be rotated, wherein the elongated member penetrates the slot (36) of each downwardly disposed plate and extends therebetween; a rotational member (50) located within each slot (36) and having an opening through which the elongated member is received; a biasing member (60) with a first end (62) and a second end (68), where at least one end engages with the rotational member (50). The biasing member (60) is adapted to drive rotation of the rotational member (50). When the tilt assembly (30) is in an unlocked position, the rotational member (50) is adapted to travel with respect to the slot (36), and when the tilt assembly (30) is in a locked position, the rotational member (50) is adapted to rotate and engage with a wail that is fixed with respect to the slot (36).

  • Patent number: 11685420
    Abstract: The present teachings relate to a spacer having a body portion and two or more opposing contact surfaces extending from the body portion, forming an angle with the body portion. The spacer may be adapted to engage with a portion of a steering column assembly to reduce or prevent rotation of a column tube during a telescoping adjustment. The teachings also include an adjustable steering column assembly having a column tube with a portion extending therefrom; a steering shaft supported for rotation at least in part by the column tube; a column housing for at least partially supporting the column tube; and the spacer. The spacer may be secured to the column tube to reduce or prevent rotation of the column tube. The teachings further contemplate a method of limiting rotational travel of a column tube during telescoping adjustment using the spacer.

  • Patent number: 9783223
    Abstract: A steering column assembly (100) and method for an automotive vehicle, comprising: an inner column tube (102), a steering shaft (104), at least one bracket structure, such as a top bracket (106), adapted for receiving a least a portion of the steering shaft and for mounting the steering column assembly within the automotive vehicle, the at feast one bracket structure (e.g., top bracket) including a side wall (124). A column housing (110) is pivotally coupled with the at least one bracket structure. An adjustable spacer (130) is disposed between the column housing and the top bracket and is mounted to the side wall of the at least one bracket structure by a single fastener (128), by a generally vertically oriented fastener adapted for allowing lateral translation (e.g., by sliding) for position adjustment of the spacer or both. The exposed surface of the spacer is in facing relation with a part of the column housing for contacting the column housing during a tilt adjustment.
