Abstract
Abstract A spine support comprises at least one bending element ( 20, 20′ ) a plurality of supporting elements ( 30 ) essentially orthogonal arranged to the at least one bending element ( 20 ) and connected with it; and a first operating element ( 40, 40′ ) arranged such that its operation leads to a bending of the at least one bending element ( 20 ). Two pairs of bowden cables ( 40, 60 ) for adjusting the spine support are operated by a control unit ( 90 ) comprising two coaxially arranged axles ( 91, 92 ). Preferably on at least one of the axles ( 91, 92 ) a receiver ( 96 ) for the inner steel cables of one of the two pairs of bowden cables and a receptacle ( 97 ) for the corresponding covers of the bowden cables are provided. The receiver ( 96 ) and the receptacle ( 97 ) approach each other or move away from each other under a rotation of the axle, depending on the direction of the rotation. The relative movement of the receiver ( 96 ) and the receptacle ( 97 ) is preferably achieved by the use of left-handed and right-handed threads on the axle.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
230 words
Adjustable spine support, in particular for a car seat, comprising a. at least one bending element ( 20 , 20 ′); b. a plurality of supporting elements ( 30 ), which are essentially orthogonally arranged on the at least one bending element ( 20 ) and which are connected to it; c. at least two Bowden cables ( 40 , 60 ) arranged such that the operation of the first Bowden cable ( 40 ) causes a bending of the at least one bending element ( 20 ) and that the operation of the second Bowden cable ( 60 ) causes a vertical adjustment of the spine support, wherein d. the first and the second Bowden cable ( 40 , 60 ) are operated by a control unit ( 90 ) with two coaxially arranged axles ( 91 , 92 ), which comprise each a section with opposed threads ( 94 ) having a receptacle ( 96 ) for an inner steel cable and a support ( 97 ) for an outer sheath of the corresponding Bowden cable ( 40 ) arranged thereon so that under a rotation ( 91 , 92 ) of one of the axles ( 91 , 92 ) the distance between the corresponding receptacle ( 96 ) and the corresponding support ( 97 ) is, depending on the direction of the rotation, decreased or increased.
Claim 2
Dependent Claim
230 words
Adjustable spine support, in particular for a car seat, comprising a. at least one bending element ( 20 , 20 ′); b. a plurality of supporting elements ( 30 ), which are essentially orthogonally arranged on the at least one bending element ( 20 ) and which are connected to it; c. at least two Bowden cables ( 40 , 60 ) arranged such that the operation of the first Bowden cable ( 40 ) causes a bending of the at least one bending element ( 20 ) and that the operation of the second Bowden cable ( 60 ) causes a vertical adjustment of the spine support, wherein d. the first and the second Bowden cable ( 40 , 60 ) are operated by a control unit ( 90 ) with two coaxially arranged axles ( 91 , 92 ), which comprise each a section with opposed threads ( 94 ) having a receptacle ( 96 ) for an inner steel cable and a support ( 97 ) for an outer sheath of the corresponding Bowden cable ( 40 ) arranged thereon so that under a rotation ( 91 , 92 ) of one of the axles ( 91 , 92 ) the distance between the corresponding receptacle ( 96 ) and the corresponding support ( 97 ) is, depending on the direction of the rotation, decreased or increased.
Claim 3
Dependent Claim
23 words
Adjustable spine support according to claim 1 where the at least one bending element ( 20 , 20 ′) comprises a coil spring.
Claim 4
Dependent Claim
46 words
Adjustable spine support according to claim 2 comprising two vertical bending elements ( 20 , 20 ′) where the plurality of supporting elements ( 30 ) consist of lath-like elements connected with the two bending elements ( 20 , 20 ′) to form a flexible framework.
Claim 5
Dependent Claim
36 words
Adjustable spine support according to claim 3 , where the two bending elements ( 20 , 20 ′) have a different distance from each other in the center of the spine support than at its ends.
Claim 6
Dependent Claim
34 words
Adjustable spine support according to claim 3 where reinforcing elements ( 26 ) are arranged around the bending elements ( 20 ) to influence the bent shape of the bending elements ( 20 ).
Claim 7
Dependent Claim
102 words
Adjustable spine support according to claim 3 where the first Bowden cable ( 40 ) is essentially parallel arranged to the two bending elements ( 20 , 20 ′), where the end of the Bowden cable ( 40 ) is mounted to the top most lath-like element ( 31 ) and where the sheath is mounted to the lowest lath-like element ( 32 ) so that an operation of the Bowden cable ( 40 ) causes the top most and the lowest lath-like element to approach each other under a simultaneous bending of the two bending elements ( 20 , 20 ′).
Claim 8
Dependent Claim
64 words
Adjustable spine support according to claim 6 , where the bending elements ( 20 , 20 ′) and the lath-like elements ( 30 ) are height adjustably suspended in the frame ( 10 ) by at least one sliding block ( 80 ) which can be upwardly and downwardly moved with a second Bowden cable ( 60 ) in the frame ( 10 ).
Claim 9
Dependent Claim
73 words
Adjustable spine support according to claim 7 where the at least one sliding block ( 80 ) is downwardly pulled by the second Bowden cable ( 60 ) under a simultaneous action on at least one restoring element ( 70 ) and where the sliding block is under a release of the tension in the second Bowden cable ( 60 ) upwardly pushed by the at least one restoring element ( 70 ).
Claim 10
Dependent Claim
25 words
Adjustable spine support according to claim 1 where the at least one bending element ( 20 ) consists of hingedly connected rods ( 20 ′).
Claim 11
Dependent Claim
19 words
Adjustable spine support according to claim 1 where the two axles ( 91 , 92 ) are manually rotated.
Claim 12
Dependent Claim
24 words
Adjustable spine support according to claim 10 where the two axles ( 91 , 92 ) are rotated by at least one electric motor.
Claim 13
Dependent Claim
33 words
Adjustable spine support according to claim 11 where the at least one electric motor is electronically controlled so that an adjusted arch and a vertical position of the spine support can be stored.
