Abstract: Light headrest optimised for production resources, comprising a head piece and bars made by overmolding on rigid cores, where said headrest is a single-piece structural body that comprises the bars and the head piece. Method for obtaining the headrest comprising the stages: (i) coupling the two rigid cores inside the injection mold having the final shape of the headrest; (ii) injecting the fused material in the mold and overmolding on the rigid cores; (iii) opening the mold and extracting the finished headrest; (iv) placing polymeric foam in the empty spaces of the single-piece structural body.

Abstract: A guide sleeve for support bar of a motor vehicle seatback headrest, comprising a hollow, plastic tube fitted with an axial passage and comprising at its upper end an integral flange segment through which runs the tube's axial passage, further a slider guided in sliding manner in a flange segment aperture perpendicularly to the axis of said passage, and fitted with an external grip and an axial continuous passage which can be aligned with the stem's axial passage respectively the flange segment's aperture, the slider moreover comprising a locking segment which may be made to engage with or disengage from a snap-in notch of the support bar as a function of slider position, further with spring elements acting on the slider and biasing it toward the snap-in notches, said spring elements being constituted by a resilient, integral slider segment resting against a wall segment of the aperture.
