Headrest for a vehicle
First Claim
1. A headrest for a vehicle seat, the headrest comprising:
- a base fixed to the seat;
a main body shiftable horizontally forward and rearward relative to the base;
a support part shiftable horizontally forward and rearward relative to the base and to the main body and engageable with a back of a head of an occupant of the seat;
a pair of levers having first ends pivoted on the base at horizontally spaced parallel axes and second ends spaced from the first ends;
pivots between the main body and locations on the levers between the respective first and second ends coupling the main body to the base for horizontally forward and rearward shifting the main body relative to the base on rotation of the levers on the base in forward and rearward directions; and
respective pivots between the second ends and the support part coupling the support part to the main body for horizontally shifting the support part codirectionally with the main body on rotation of the levers on the base in the forward and rearward directions.

Abstract
A headrest (10) for a vehicle seat has at least one base (11), such as a support rod or the like. A main body (12) is held on the base (11). A support part (13) having a head support surface (44) can move relative to the main body (12) forward in the forward direction (x) toward the back of the head of the vehicle occupant and back in the rearward direction (z).
The main body (12) is movable on the base (11) and can be shifted by at least one rotatable transmission element (K1; 28, 30) in the forward direction (x) and in the rearward direction (z). At the same time, the support part, which moveable in the same direction with the main body (12) in the forward direction (x) and the rearward direction (z), is pivoted on the same rotatable transmission element (K1; 28, 30).

5. A headrest for a vehicle seat, the headrest comprising:
-
a base; a main body having a first extension projecting in a forward direction toward the back of a head of a vehicle occupant and forming a first coupling link; levers supporting the main body on the base for movement in the forward direction and back in an opposite rearward direction and centrally pivoted on the extension; and a support part having a head support surface, pivoted on the levers so as to be movable in the same direction as the main body relative to the main body in the forward direction and in the rearward direction, and having a second extension protecting rearward and forming a second coupling link carrying pivots each on an end of a respective lever extending away from the extension of the base. - View Dependent Claims (6, 7, 8, 9)
