Problems solved by technology

[0006] In addition, unlocking with a constant and too small force creates no resistance for the operator and thus renders the adjustment process impractical
[0007] Additionally, unlocking may occur unexpectedly due to excessive shock and vibration

Embodiment Construction

[0031] The device according to the invention is intended to be fitted on the steering column body 5 of a motor vehicle. The body 5 is at least partially shown in the figure.

[0032] A steering column (not shown) can be adjusted in longitudinal movement and height to accommodate drivers of varying sizes.

[0033] However, adjustment of the steering column is only possible when the steering column is released from the fixed and secure part which holds the steering column firmly in its functional position on the body. The steering column adjustment system is not shown here.

[0034] After each adjustment, it is necessary to re-block the steering column and its adjustment system in the desired position and to assure the driver that the steering column is properly locked.

[0035] Likewise, during unlocking for regulatory purposes, it is advisable to give the operator some assistance and information about the state of the system.

[0036] In this respect, as shown, the auxiliar...

Abstract

The present invention relates to a device for the assisted locking and unlocking of an adjustable steering column comprising a fixed cam element (2) secured to a column body (5), a moving cam element (1) extended by an operating lever (11), and articulation means coupled to a central spindle (3) mounted between the said elements and passing through the said body, characterized in that the said articulation means comprise an elastic return member (4) intended to collaborate with two sets of complementary bosses (12, 21) borne respectively by each cam element (1, 2) and delimiting, with one another, two end-of-travel stops so that by pivoting the lever (11), the moving cam element (1) can be made to move between a locked position and an unlocked position via an intermediate position of unstable equilibrium.

Description

technical field [0001] The invention relates to a device for assisting locking and unlocking of an adjustable steering column. [0002] More specifically, the present invention relates to mechanisms for assisting the locking and unlocking of the steering column in order for the driver to adjust the steering column. Background technique [0003] Locking devices that already exist in the prior art include: a fixed cam element, which is fixed to the cylinder; a movable cam element, which extends through the operating lever; The central mandrel is connected. [0004] However, these devices do not provide sufficient sensitivity or optimal functional differentiation to the user. [0005] In fact, in the unlocked position, there is a gap between the movable cam and the fixed cam element, which creates a false impression. [0006] In addition, unlocking with a constant and too low force would result in no resistance being felt by the operator, thus rendering the adjustment proces...
