Abstract

A seat height adjuster for a vehicle seat consisting of a carrier plate, a base plate connected to the carrier plate by a sliding guide and with an adjustment mechanism with an electrical drive for adjusting the carrier plate to the base plate, wherein the base plate can be mounted on a seat trough, wherein the seat height adjuster can be mounted on the seat trough with a manual drive or an electrical drive.

Description

Seat Height Adjustment The present invention relates to a seat height adjustment.
Prior art Refer in the prior art to DE 10 2009 018 754 Al, in which the drive is built into a seat trough.
The energy is subsequently transferred via a flexible shaft from the seat trough into an adjusting mechanism in the seat height adjuster.
Problem of the invention There is the problem in seat height adjustments from the prior art that, for example, the electronic drive was received in the seat trough. This, for its part, has, however, the disadvantage that the seat trough is overloaded at times with other components such as control devices, plug receptacles, cable fastenings, drawers or fans and that the additional integration of a drive poses problems.
Solution of the problem A seat height adjuster according to the invention is designed for a vehicle seat. The vehicle seat is designed for being built into a motor vehicle or a truck or a boat or an airplane.
The seat height adjuster consists of a carrier plate and a base plate.
Furthermore, the seat height adjuster comprises a drive that can move the carrier plate to the base plate.
The moving takes place here by a cooperation of an adjusting mechanism with a sliding guide.
The adjusting mechanism serves to move the carrier plate to the base plate.
The sliding guide ensures that during the shifting a linear lateral movement is achieved without the carrier plate being able to be removed from the base plate, whereby the base plate can be mounted on a seat trough.
The manual drive and/or the electrical drive are designed in such a manner that the seat height adjuster should be able to be mounted on one and the same seat trough construction independently of whether it has a manual drive or an electrical drive.
Furthermore, the seat height adjuster in accordance with the invention is designed for an electrical drive in such a manner that the electrical drive is arranged on the carrier plate. The arrangement of the electrical drive is on the carrier plate, as is also the case, for example, for a manual drive. It is primarily of no importance, in which position of the carrier plate the electrical drive is arranged. In a preferred exemplary embodiment the electrical drive is arranged on the bottom of the carrier plate. The bottom of the carrier plate is the side of the carrier plate that faces the base plate in a proper mounting. An electromotor requires the most space. Therefore. an electromotor is arranged on a part of the carrier plate that extends over the circumference of the baseplate. The baseplate is firmly connected to the seat trough. Upon a moving of the carrier plate away from the base plate the electromotor is entrained with it.
It is especially advantageous that all essential parts of the seat height adjustment can be screwed onto a scat trough regardless of whether an electrical drive or a manual drive is used for the adjustment of the seat height. This means that even an electrical drive can be integrated into the seat height adjustment, as already takes place in the case of the manual drive, by a low total construction height. As a result, the same seat trough is always used, regardless of whether an electrical or a manual drive is used, since, for example, no recesses are used any more in the seat trough in order to bring the energy of an electromotor located in the seat trough via a shaft into the seat height adjuster.
2 The electrical drive also comprises a transmission in addition to the electromotor. In another exemplary embodiment the electrical drive is a spindle drive. The spindle is arranged substantially at a right angle to the electromotor. In this exemplary embodiment the base plate has a U-shaped recess into which the spindle extends. Furthermore, the spindle drive comprises a spindle anchor that makes possible a moving of the carrier plate to the base plate. The spindle is rotated by the spindle anchor, adjusting the carrier plate to the base plate.
In another exemplary embodiment either the entire electrical drive or a part of the electrical drive can be clipped onto the carrier plate. That means that a part of the electrical drive or, for example, only the electromotor can be clipped on without other fastening means such as screws or adhesives. To this end the carrier plate comprises appropriate receptacles into which the electrical drive or parts of the electrical drive can be clipped in by overcoming a first resistance.
The clipped-in parts of the electrical drive should slide out only during proper usage.
In addition, the manual drive comprises a catch mechanism activated by a lever. Upon activation of the lever the catch mechanism is released and the user can shift the carrier plate to the base plate. The lever is connected by an activation clement to the catch mechanism.
When the desired position has been reached, the user can, for example, let go of the lever and the catch mechanism re-engages so that the carrier plate is fixed on the base plate. Since the individual parts of the seat height adjuster are to be manufactured from plastic to the extent possible, reinforcing devices are required. Therefore, in an exemplary embodiment according to the invention the carrier plate and the baseplate comprise appropriate reinforcement ribs.
Description of the figures Other advantages, details and features result from the following description of the figures. The figures show in detail in

Fig. 2 an oblique view from above onto the seat height adjuster according to figure 1;
Fig. 3 a view from below onto the seat height adjuster according to figure 1 ;
Fig. 4 a lateral view of the seat height adjuster according to figure 1;
Fig. 5 a front view of the seat height adjuster according to figure 1:
Fig. 6 a perspective view from above onto a seat height adjuster according to another exemplary embodiment:
Fig. 7 a perspective view from below onto the seat height adjuster according to figure 6; and Fig. 8 a bottom view of the seat height adjuster according to figure 6.
Figure I shows a seat height adjuster according to the invention. The seat height adjuster according to the invention comprises a carrier plate 1 and a base plate 2.
Furthermore, an electrical drive 3 is shown that consists of an electromotor, a transmission 5 and a spindle 6.
The electrical drive 3 is attached to the bottom of the carrier plate 1.
"Bottom" means here the side of the carrier plate 1 that faces the base plate 2. Moreover, a spindle anchor 7 is shown through which the spindle 6 extends. The spindle anchor 7 brings it about in conjunction with the electromotor 4 and the transmission 5 that the spindle 6 rotates in the spindle anchor 7 and moves the carrier plate 1 to the base plate 2.
According to the invention the electrical drive 3 is connected to the carrier plate 1 in such a manner that retains its position relative to the base plate 2 during the shifting of the carrier plate 1. This can take place, for example, in that the drive 3 can be clipped in prefabricated recesses present on the bottom of the carrier plate 1. However, it can also take place in that the electrical drive 3 is screwed fast on the bottom of the carrier plate 1. Furthermore, figure 1 shows how
4 the carrier plate 1 comprises reinforcement ribs 9 and the base plate 2 comprises reinforcement ribs 8.
Figure 2 shows a top view of figure 1. The carrier plate 1 can be recognized again in it.
Figure 3 shows a bottom view onto the seat height adjuster. The base plate 2 comprises openings 10.1 to 10.4 there that serve to fasten the base plate 2 to a seat trough (not shown).
Furthermore, longitudinal struts 11.1, 11.2 can also be recognized that represent a part of a sliding guide. The sliding guide is constructed in such a manner that the carrier plate 1 can be shifted to the base plate 2 in such a manner that it cannot be raised from the base plate 2. The longitudinal struts 11.1, 11.2 also indicate the contours of the base plate 2 as a demarcation to the carrier plate 1.
Different views of the features already shown and explained in the previous figures can be recognized again in the figures 4 and 5. A repetition will not be made.
Figure 6 shows another exemplary embodiment of a seat height adjuster. Here, a manual drive can be recognized instead of the electrical drive 3. The manual drive consists of a lever 12, an activation element 13 and a catch mechanism that is not shown in detail.
The user pulls the lever 12 away from the base plate 2, activating the catch mechanism, that had locked the carrier plate 1 to the base plate 2 up to then. The lever 12 is spring-supported so that it snaps back when the user lets go of the lever 12. After the user has activated the lever 12 and the catch mechanism was unlocked, he pulls the carrier plate 1 with the aid of the activation element 13 away from the base plate 2. As soon as the user has reached the desired position he lets go of lever 12 and the catch mechanism firmly holds the carrier plate 1 in the desired position to the base plate.

Furthermore, figure 7 also shows screw elements 14.1 to 14.3 that are thrust through the openings 10.1 to 10.3. The screw elements 14.1 to 14.3 serve to locally fix the base plate 2 to a seat trough (not shown in detail).
Refer regarding the remaining features to the description of the figures 1 to
5. In particular, the explanations for features should be used if they have the same reference numbers.
It can be recognized especially well in figure 8 how the lever 12 is connected to the fastening element 13. Otherwise, refer to the above explanations.
