Embodiment Construction

[0019] Such as figure 1 As shown, the lumbar support comprises two external pneumatically operated first chambers 11 and 12 , these being a lower chamber 11 and an upper chamber 12 . The two outer cavities 11 and 12 each have an air connection to one of the two central second cavities 13 , 14 positioned above each other perpendicularly to the longitudinal direction of the lumbar support. as (especially) figure 2 As shown, in each case, the lower chamber 11 and the upper chamber 12 comprise air supply lines 21 and 22, respectively, by means of which air supply lines 21 and 22 are used to control the supply of air to or from the chambers 11 and 12. remove the air. exist figure 2 In the representation shown, chamber 11 is connected to supply air to chamber 14 via connection 23 . Likewise, cavity 12 includes an air connection (not shown) to cavity 13 . If the chamber 12 is then fed with compressed air via the air supply line 22 , the chamber 12 is filled with compressed air...

Abstract

The invention relates to a lordosis support which has a plurality of pneumatically operated chambers (11-14) for adjusting the curvature of a seat back, with the lordosis support having two outer chambers (11, 12) and two central chambers (13, 14) in the longitudinal direction of the seat back, with the two central chambers (13, 14) being arranged one above the other between the two outer chambers perpendicular to the longitudinal direction of the seat back, with an air connection to one of the two central chambers being provided for each outer chamber.

Description

technical field [0001] The present invention relates to a lumbar support comprising a plurality of pneumatically operated cavities for adjusting the curvature of a seat back. Background technique [0002] Such lumbar supports are used, for example, in the backrests of motor vehicle seats. In such cases, the lumbar support has multiple support functions because both the lower (i.e., lumbar or lordotic) and mid- and upper spinal regions must be properly supported in order to reliably prevent relatively long-term Symptoms of fatigue during sitting and possible damage to health. For this reason, it is extremely important to use a lumbar support with an adjustable arch or curvature in order to be able to adapt the apex of the curve to the individual requirements of a particular person sitting on the seat. However, this applies not only to lumbar supports in motor vehicle seats, but also to backrests of any type of seat (eg office chairs). [0003] Such a lumbar support may be ...
