Tilt device for steering column

Abstract

Abstract PURPOSE:To facilitate the work on a tooth section and make it compact by providing a ratchet and a tooth plate that can be connected and disconnected to said ratchet at a tilt bracket or fixed bracket and enabling the angle of revolution of tooth plate to be extended in relation to the angle of revolution of the tilt bracket. CONSTITUTION:When a tilt lever 36 is depressed clockwise around a pin 34 for tilt actuation, a roller 43 is disconnected from the cam surface 43b of a ratchet 40 and simultaneously is engaged in an engagement groove 42a and then the ratchet 40 is revolved clockwise. As a result, the engagement between upper and lower teeth 38 and 41 is released and a tilt bracket 24 is rotated counterclockwise by a spring 31. In this case, a tooth plate 37 is also revolved around the pin 34 by the relative movement between the guide pin 33 of a bracket 24 and the long hole 39 of a tooth plate 37. After the optimum position of a steering wheel is fixed in this state, the lever 36 is released and the tilt bracket is restrained by the engagement of both teeth 38 and 41.
