Description

[0001] The invention relates to a device for reversibly adjusting a steering column of a motor vehicle from a working position to an easy-entry position according to the preamble of claim 1. The invention further relates to a steering system for a motor vehicle. State of the art

[0002] Steering column mounts, which can be fixed or adjustable, are well-known. In passenger cars, in particular, steering column mounts with electrically operated adjustment mechanisms are common, allowing for adjustment of the steering column's height and / or tilt. Such steering column mounts are also known in the commercial vehicle sector. However, electrically operated adjustments are very slow and limited to a relatively small adjustment range. Especially in the commercial vehicle sector, steering column mounts with a large adjustment range are required. For this purpose, designs are typically used where the steering column can generally be manually pivoted into a near-vertical position to facilitate entry into and exit from the vehicle.

[0003] DE 10 2009 001 324 A1 discloses a steering column bracket with a support housing for a steering column which is mounted in a steering column receptacle which is at least rotatably arranged, whereby at least the inclination of the steering column can be changed and wherein at least a first detent and a second detent are provided which can be connected to the support housing, and that a quick-release device for locking into one of the detent positions is provided, whereby the steering column can be locked into a first inclination position or into a second inclination position.

[0004] The quick-release device allows the rotatably mounted or pivotable steering column mount to be adjusted essentially between two end positions, with the lower end position precisely determining the desired and preset driving position.

[0005] It is desirable that the steering column mount is not only adjustable between two end positions, but can also be reversed from any operating position to an easy-entry position.

[0006] This problem is solved by a device for reversibly adjusting a steering column of a motor vehicle from a service position to an easy-entry position, having the features of claim 1. Furthermore, the problem is solved by a steering system for a motor vehicle having the features of claim 10. Disclosure of the invention

[0007] The present invention provides a device for reversibly adjusting a steering column of a motor vehicle from a working position to an easy-entry position, comprising a bearing block in which a steering column housing of the steering column is adjustably mounted, first guide means by which the steering column housing is adjustable in height, and second guide means by which the steering column housing is adjustable in inclination, wherein the first guide means and the second guide means are designed to mechanically move the steering column housing from the working position, which can be determined within a height and inclination adjustment range of the steering column housing, into the easy-entry position and back into the previous working position.

[0008] The invention further provides a steering system for a motor vehicle, comprising a device for reversibly adjusting a steering column of a motor vehicle from a working position to an easy-entry position and a steering column housing of the steering column which is adjustably mounted by the device.

[0009] One idea of ​​the present invention is to provide a device which makes it possible to reversibly adjust the steering column mount from any operating position to an easy-entry position.

[0010] The steering column housing is designed to have at least one guide pin, which is inserted into at least one guide slot of the bearing block and is movable along the guide slot of the bearing block. The first guide means are connected at a first axial end section to the at least one guide pin and at a second axial end section to at least one further guide pin inserted into the at least one guide slot of the bearing block. Thus, the first guide means can move with the steering column housing along the guide slot during height adjustment of the steering column housing.

[0011] It is provided that the first guidance means comprise at least a first guidance element and at least a second guidance element, which are arranged to be telescopically slidable within one another, wherein the at least one first guidance element can be inserted into the at least one second guidance element. Thus, a compact dimension of the first guidance means as well as telescopic adjustability of the first guidance element relative to the second guidance element of the first guidance means can be achieved.

[0012] It is provided that the first guide element is connected at a first axial end section to the at least one guide pin and is inserted at a second axial end section into the at least one second guide element, wherein the at least one second guide element has an opening at a first axial end section for receiving the at least one first guide element and is connected at a second axial end section to at least the further guide pin inserted into the at least one guide slot of the bearing block. Thus, it can be achieved that the first guide elements can be securely attached to an inner or outer surface of the bearing block.

[0013] It is provided that at least one second guide element can be locked in a specific position within an adjustment range of the first guide means along the at least one guide slot of the bearing block by a first fastening device of the bearing block, wherein the first fastening device of the bearing block has a jaw connected to the further guide pin, which can be pressed against the bearing block by a Bowden cable. This allows the second guide element to be effectively locked.

[0014] Advantageous embodiments and further developments are described in the dependent claims and in the description with reference to the figures.

[0015] According to a preferred embodiment, the second guide means comprise at least a third guide element and at least a fourth guide element, which are connected to the further guide pin inserted into the at least one guide slot of the bearing block and are rotatably mounted on the further guide pin. The at least one third guide element is connected to the steering column housing by a spacer plate such that the at least one third guide element is rotatable relative to the further guide pin by a deflection of the spacer plate caused by adjusting the tilt of the steering column housing. The second guide means thus comprise a guide element that rotates relative to the guide pin when the tilt of the steering column housing is adjusted.

[0016] According to a further preferred embodiment, it is provided that the at least one fourth guide element can be locked in a determinable position within an adjustment range of the second guide means by a second fastening device of the bearing block, in which the second guide means are rotatable relative to the further guide pin, wherein the second fastening device of the bearing block has a first toothed element and a second toothed element, wherein a first section of the first toothed element is in engagement with the fourth guide element and a second section of the first toothed element can be brought into engagement with the second toothed element by means of a Bowden cable for locking the fourth guide element.Thus, the fourth guide element can be locked onto the guide bolt, so that it no longer moves along with the third guide element, which is connected to the spacer plate, when the tilt of the steering column housing is adjusted.

[0017] According to a further preferred embodiment, the device for reversibly adjusting the steering column of the motor vehicle can be activated by actuating the first fastening device and the second fastening device, wherein the first fastening device and the second fastening device are integrally designed and can be actuated together, and wherein the first fastening device and / or the second fastening device comprise a pneumatic pressure piston, a hydraulic pressure piston or an electromechanical clamping device.By actuating the fastening device, the device for reversibly adjusting the steering column of the motor vehicle can thus be switched from a first mode, in which the height and tilt of the steering column can be adjusted normally, to a second mode, in which the steering column of the motor vehicle can be reversibly adjusted from a working position to an easy-entry position and back to the previous working position.

[0018] According to a further preferred embodiment, when adjusting the height of the steering column housing in a deactivated state of the device, the at least one first guide element and the at least one second guide element are arranged telescopically displaced within one another, and the first guide elements are movable along the at least one guide slot of the bearing block in this state. Thus, in the deactivated state of the device, in which the first and second guide elements are not required, the first and second guide elements advantageously have compact dimensions.

[0019] According to a further preferred embodiment, when the steering column housing is moved from the operating position to the easy-entry position in an activated state of the device, the at least one second guide element locks in the determinable position within the adjustment range of the first guide means along the at least one guide slot of the bearing block, and the at least one first guide element can be moved along with the steering column housing by extending from the at least one second guide element. This enables a memory effect with respect to the height adjustment of the steering column housing, since, due to the locking of the second guide element, when the steering column housing is returned from the easy-entry position to the previous operating position, the first guide element simply needs to be telescopically retracted into the second guide element.

[0020] According to a further preferred embodiment, when the tilt of the steering column housing is adjusted in a deactivated state of the device, the at least one third guide element is rotatable relative to the further guide pin by the deflection of the spacer plate caused by the tilt adjustment of the steering column housing, wherein the at least one fourth guide element is operatively connected to the at least one third guide element such that, when the spacer plate is deflected by the tilt adjustment of the steering column housing, the at least one third guide element and the at least one fourth guide element are together rotatable relative to the further guide pin. Thus, tilt adjustment of the steering column housing is advantageously possible in the deactivated state of the device.

[0021] According to a further preferred embodiment, when the steering column housing is moved from the operating position to the easy-entry position in an activated state of the device, the at least one fourth guide element locks in the determinable position within the adjustment range of the second guide means, and the at least one third guide element can be moved along with the spacer plate connected to the at least one third guide element and is rotatable relative to the further guide pin, wherein the at least one fourth guide element has a stop against which the at least one third guide element can be abutted when returning from the easy-entry position to the previous operating position. Thus, a memory function with respect to the tilt position of the steering column housing can be achieved.When the steering column housing is returned from the easy-entry position to the previous operating position, the third guide element is advantageously reset until it contacts the stop of the fourth guide element.

[0022] According to a further preferred embodiment, the bearing block comprises a first bearing plate and a second bearing plate arranged at a predetermined distance, essentially parallel to it, which are connected to each other by at least one connecting element. The steering column housing is adjustably mounted between the first and second bearing plates. The bearing block has a guide slot formed in the first bearing plate and a further guide slot formed in the second bearing plate. The steering column housing, in which the steering column is received, is thus preferably adjustable in height along the guide slots formed in the first and second bearing plates.

[0023] The described configurations and training programs can be combined in any way desired.
