Abstract
Abstract This invention relates to a neck support for car seats having a support roll in form of a support cushion, a lever and a fixing device, said lever being connected by stop devices as well to the cushion as to the fixing device, which is fixed in such a manner to the back rest of the car seat, that it can be brought and secured in several positions relatively to the back rest, in which said stop devices which connect the cushion to the lever are at least almost identical to those which connect said lever to the fixing device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
177 words
A safety neck support for car seats comprising a support cushion, a supporting lever and a fixing device for connecting the neck support to the back rest of the car seat, said lever being pivotably mounted in said support cushion by means of first pivot means and in said fixing devices by means of second pivot means, each of said first and second pivot means comprising lock means preventing relative rotation of said cushion on said lever and of said lever on said fixing device respectively, said lock means being engaged by spring force and being disengageable by pressure on said cushion and lever respectively in the direction of the axis of said first and second pivot means, and said lock means having symmetrical characteristics such that they are disengageable by axial pressure in both directions, it being possible to simultaneously disengage both lock means by axial pressure against said cushion for horizontal and vertical adjustment of the cushion by swivelling the cushion relatively to said lever and by swivelling said lever relatively to said fixing device.
Claim 2
Dependent Claim
177 words
A safety neck support for car seats comprising a support cushion, a supporting lever and a fixing device for connecting the neck support to the back rest of the car seat, said lever being pivotably mounted in said support cushion by means of first pivot means and in said fixing devices by means of second pivot means, each of said first and second pivot means comprising lock means preventing relative rotation of said cushion on said lever and of said lever on said fixing device respectively, said lock means being engaged by spring force and being disengageable by pressure on said cushion and lever respectively in the direction of the axis of said first and second pivot means, and said lock means having symmetrical characteristics such that they are disengageable by axial pressure in both directions, it being possible to simultaneously disengage both lock means by axial pressure against said cushion for horizontal and vertical adjustment of the cushion by swivelling the cushion relatively to said lever and by swivelling said lever relatively to said fixing device.
Claim 3
Dependent Claim
87 words
A safety neck support according to claim 1, wherein each of said first and second pivot means has a shaft with a toothed portion near each of its ends, each of said toothed portions engaging a toothed portion of a pivot member when said shaft and pivot member are maintained in a rest position by said spring force, and said toothed portions being axially disengaged thereby allowing relative rotation of said shaft and said pivot members by axial forces acting between said shaft and said pivot members.
Claim 4
Dependent Claim
83 words
A safety neck support according to claim 2, wherein said shaft is a hollow shaft having an internal toothing while said pivot members engage into the ends of said hollow shaft and are provided each with an external toothing, said internal toothing of the hollow shaft and said external toothing of the pivot members engaging each other in a rest position of said hollow shaft determined by springs acting each between one of said pivot members and an abutment in said hollow shaft.
Claim 5
Dependent Claim
69 words
A safety neck support according to claim 1, wherein said cushion is of substantially circular cross section, said first pivot means being located near the circumference of said cushion such that substantially vertical adjustment of the cushion is obtained by pivoting it round said first pivot means but the shape of the portion of the cushion supporting the head being substantially independent of the vertical position of the cushion.
