Abstract
Abstract This invention discloses a device for setting the position of reclining seat backs of vehicles comprises a stationary bracket connected to the seat and a movable bracket connected to the seat back and pivoted to said stationary bracket. The stationary bracket includes a slideway provided in the stationary bracket, a slider adapted to slide along said slideway, an actuating means fastened to the usual control knob and means for engagement of said slider with said movable bracket. The engagement means are arranged at a location offset with respect to the pivotal axis of said movable bracket so as to provide a crank arm capable of angularly moving said movable bracket.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
194 words
A device, particularly adapted for the adjustable setting of the position of a reclining seat back icluding a stationary bracket fixedly secured to a seat portion, a movable bracket fixedly secured to a seat back, and means for interconnecting said stationary and movable brackets; one of said stationary and movable brackets including a U-shaped slideway, the other of said stationary and movable brackets including a first portion of a crank arm means; said means for interconnecting including a slider adapted to be confined by and to slide rectilinearly along said slideway, an actuating means actuated by a control knob for transforming the rotational motion imparted to said control knob into a rectilinear motion of translation of said slider, and a pivot means; said slider including a second portion of said crank arm means, and a laterally projecting means for engagement by said actuating means; said crank arm means being arranged at a location offset with respect to the pivot means interconnecting said movable bracket and said stationary bracket so as to provide a crank arm capable of angularly moving said movable bracket and thereby said seat back upon rotational actuation of said control knob.
Claim 2
Independent Claim
194 words
A device, particularly adapted for the adjustable setting of the position of a reclining seat back icluding a stationary bracket fixedly secured to a seat portion, a movable bracket fixedly secured to a seat back, and means for interconnecting said stationary and movable brackets; one of said stationary and movable brackets including a U-shaped slideway, the other of said stationary and movable brackets including a first portion of a crank arm means; said means for interconnecting including a slider adapted to be confined by and to slide rectilinearly along said slideway, an actuating means actuated by a control knob for transforming the rotational motion imparted to said control knob into a rectilinear motion of translation of said slider, and a pivot means; said slider including a second portion of said crank arm means, and a laterally projecting means for engagement by said actuating means; said crank arm means being arranged at a location offset with respect to the pivot means interconnecting said movable bracket and said stationary bracket so as to provide a crank arm capable of angularly moving said movable bracket and thereby said seat back upon rotational actuation of said control knob.
Claim 3
Dependent Claim
41 words
A device according to claim 10, wherein said stationary bracket is L-shaped and has a first leg intended to be fastened to said seat and second leg substantially at right angles to said first leg in which said slideway is provided.
Claim 4
Dependent Claim
33 words
A device according to claim 1, wherein said actuating means includes a disc having on a surface thereof a spiral groove and said laterally projecting means is adapted to engage said spiral groove.
Claim 5
Dependent Claim
46 words
A device according to claim 1, wherein said second portion of said crank arm means includes a second slot means provided in said slider and said first portion includes a pin fastened to said movable bracket, said pin adapted to slide within said second slot means.
Claim 6
Dependent Claim
69 words
A device as claimed in claim 1, wherein there are provided two sliders arranged on opposite sides of said slideway and said control knob is connected to said actuating means through outer toothings provided on both said control knob and said actuating means, said control knob having a lesser tooth number than that provided on said actuating means in order to obtain a strong reduction of the operating forces.
Claim 7
Dependent Claim
47 words
A device as claimed in claim 5, wherein said actuating means is a disc having on a surface thereof a spiral groove and each of said two sliders has a laterally projecting means adapted to engage said spiral groove, said laterally projecting means being generally ball shaped.
Claim 8
Dependent Claim
50 words
A device according to claim 5, wherein said second portion of said crank arm means includes at least one pin on each said slider and said first portion includes a pair of radially extending slots in said movable bracket, said slots adapted to receive said pin of the associated slider.
Claim 9
Dependent Claim
88 words
A device according to claim 7, wherein said stationary bracket has in its slideway a pair of slots provided on each side thereof and offset in height to each other and each of said sliders has a pin of lesser length than the pin adapted to engage the radially extending slots of said movable bracket, the two pins of each slider being adapted to be received into said slots of said slideway of said stationary bracket in order to guide the movement of said sliders within said slideway.
