Vehicular seat headrest and method
View Patent ↗The invention relates to a headrest for a vehicle, a method for producing a headrest, and a vehicle seat comprising a headrest. The headrest is provided with a body ( 2 ) and a holding element ( 3 ). A filling material ( 23 ) is provided between a connection part ( 22 ), used to connect the holding element ( 3 ) to the headrest body ( 2 ), and a cover ( 21 ). The connection part ( 22 ) and the cover ( 21 ) define an essentially tight space in relation to the filling material ( 23 ) when the filling material ( 23 ) is in the essentially liquid processing state thereof.
1. A headrest for a vehicle, in particular a motor vehicle, comprising:
a headrest body and a headrest holding element,
a cover arranged substantially on the entire outer face of the headrest body and also in the region of an outlet of the headrest holding element from the headrest body,
a connection part being provided inside the headrest body and at least partially within the confines of the cover for connecting the headrest holding element to the headrest body,
the cover extends at least partially in the region of one edge of the connection part located in the region of the outlet of the headrest holding element, the edge being provided with a small bearing surface such that the cover may sealingly bear against the edge and wherein the cover includes at least one groove and wherein the edge of the connection part is received in the at least one groove,
a foam filling material being arranged between the connection part and the cover, the filling material being provided in substantially liquid form in its processing state,
and relative to the filling material in its processing state, the connection part and the cover define a substantially sealed space.
2. The headrest as claimed in claim 1 further characterized in that the connection part has an internal volume for receiving the headrest holding element and in that, relative to the filling material in its processing state, the part of the connection part coming into contact with the filling material is sealingly provided relative to the internal volume.
3. The headrest as claimed in claim 1 wherein the cover is of one-piece of material.
4. A method for producing a headrest, said method comprising the steps of:
providing a headrest body having an outer face and a headrest holding element,
at least partially covering the outer face of the headrest body with a cover having at least one groove,
connecting the headrest holding element to the headrest body with an internal connecting part,
arranging the headrest holding element and the connection part inside the cover,
introducing the filling material in its processing state into the space between the cover and the connection part and at least whilst the filling material introduced into the headrest is in its processing state, the cover is pressed by means of a tool against the edge of the connection part such that the edge of the connection part is received in the at least one groove of the bearing surface of the cover.
