A guide sleeve for neck rests on vehicle seats adapted to slidingly accommodate a rod carrying a neck rest, the sleeve comprising an enlargement adjacent to the upper end thereof which extends transverse to the axis of the sleeve, a slider element slidably guided within the enlargement and including a manually operable portion extending outwardly of the enlargement. A pin-shaped metallic locking element is positioned in the slider element adapted to cooperate with the rod on the side opposite to the manually operable portion whereby an axial displacement of the rod is prevented. A spring element of the locking element acts on the slider element to bias the pin element towards the rod, the spring element being formed by a bent elongated spring portion of the pin-shaped locking element which is supported by a rear wall of the enlargement.

[ I claim:] [1.] A guide sleeve for neck rests on vehicle seats, comprising:bore means, defining a vertical axis of said guide sleeve, for slidably accommodating a vertically movable rod supporting a neck rest;an enlargement disposed adjacent to the upper end of said guide sleeve and extending transversely with respect to said axis of said guide sleeve, said enlargement comprising an end wall, a pair of oppositely disposed side walls connected to opposite ends of said end wall, and an open end disposed opposite said end wall;a slide element slidably guided within said enlargement between said pair of oppositely disposed side walls and toward and away from said end wall, and including a manually operable portion formed upon one end of said slide element and extending outwardly from said enlargement through said open end of said enlargement, and a pair of laterally spaced support portions, formed upon a second end of said slide element opposite said manually operable portion, and disposed upon opposite sides of said bore means;a locking element having laterally spaced end portions fixedly mounted upon each one of said laterally spaced support portions of said slide element such that said locking element is movable with said slide element within said enlargement between a first position at which a central portion of said locking element is engaged with the vertically movable rod disposed within said bore means and supporting the neck rest so as to prevent axial displacement of the rod and the neck rest supported thereby whereby the rod and the neck rest supported thereby are fixed at a first vertical position, and a second position at which said central portion of said locking element is disengaged from the vertically movable rod disposed within said bore means and supporting the neck rest so as to permit axial displacement of the vertically movable rod and the neck rest supported thereby whereby the vertically movable rod and the neck rest supported thereby can be moved to a second vertical position; andspring means engaged with said end wall of said enlargement for biasing said slide element away from said end wall of said enlargement and outwardly through said open end of said enlargement and for biasing said locking element toward said first position so as to achieve engagement of said central portion of said locking element with the vertically movable rod disposed within said bore means and supporting the neck rest, and yet permitting movement of said slide element toward said end wall of said enlargement and movement of said locking element mounted upon said slide element toward said second position against the bias of said spring means so as to achieve disengagement of said central portion of said locking element from the vertically movable rod disposed within said bore means and supporting the neck rest,wherein said spring means and said locking element comprise a one-piece integral element.
