Arrangement for a vehicle seat
View Patent ↗An arrangement for a vehicle seat includes an inner element ( 11 c, 11 d ), an outer element ( 9, 16 a ), which has an opening ( 16 b ) having an edge ( 9 c, 16 c ) and receives the inner element ( 11 c, 11 d ), and a weld seam ( 20 ) which connects the outer element ( 9, 16 a ) to the inner element ( 11 c, 11 d ). The edge ( 16 c ) of the opening of the outer element ( 9, 16 a ) is interspaced from the inner element ( 11 c, 11 d ) over the largest part of its circumference and defines a radial gap (G) having a defined maximum width, the weld seam ( 20 ) being introduced into the gap (G).
1. An arrangement for a vehicle seat comprising:
an inner element;
an outer element which has an opening provided with an edge, said opening receiving the inner element; and
a weld seam connecting the outer element to the inner element wherein the edge of the opening of the outer element is spaced apart from the inner element over a largest part of a periphery thereof, forming a radial gap with a defined minimum width, the weld seam being introduced into the gap by using a filler material, at least one bearing point being provided for forming the gap, said bearing point protruding radially from the edge of the opening of the outer element or from the inner element, wherein the arrangement is configured as a fitting for a vehicle seat, the fitting comprising at least one adjustment fitting for adjusting the inclination of a backrest of the vehicle seat relative to a seat part of the vehicle seat, said fitting comprising a free-pivoting unit for central free-pivoting of the backrest from at least one position of use into a freely-pivoted position, the free-pivoting unit comprising a latching element which may be connected to the adjustment fitting, a third fitting part which is rotatably mounted relative to the latching element about an axis and which is connected to the backrest and a pawl which in the position of use locks the third fitting part to the latching element and in that the latching element includes a collar and forms the outer element, while the adjustment fitting forms the inner element.
2. The arrangement as claimed in claim 1 wherein the third fitting part is mounted on the collar of the latching element.
3. The arrangement as claimed in claim 1 wherein the third fitting part is axially arranged between the latching element and the adjustment fitting.
4. The arrangement as claimed in claim 3 , wherein the third fitting part on the side remote from the adjustment fitting is axially secured by means of the latching element.
5. The arrangement as claimed in claim 1 wherein the free-pivoting unit has a pretensioned clamping element for securing the locked pawl in the normal case and a capture element for supporting the pawl in the event of a crash.
6. A vehicle seat comprising:
a seat part;
a backrest; and
an arrangement for a vehicle seat comprising:
an inner element with an outer surface;
an outer element with an edge defining an opening having an inner surface, said opening receiving the inner element, one of said outer surface and said inner surface defining at least a bearing portion;
a weld seam connecting the outer element to the inner element, the inner surface of the outer element being spaced apart from the outer surface of the inner element over a part of a periphery of the edge by said bearing portion, said bearing portion protruding radially from the edge of the opening of the outer element or from the inner element and forming a radial gap with a defined minimum width, the weld seam comprising filler material introduced into the gap, said bearing portion engaging the other one of said outer element and said inner element to define a bearing point; and
a fitting including an adjustment fitting for adjusting the inclination of the backrest relative to the seat part, said fitting comprising a free-pivoting unit for central free-pivoting of the backrest from at least one position of use into a freely-pivoted position, said free-pivoting unit comprising a latching element for connection to the adjustment fitting, wherein a third fitting part is rotatably mounted relative to the latching element about an axis and is connected to the backrest, wherein a pawl for, in the position of use, locking the third fitting part to the latching element, said latching element including a collar and forming the outer element, said adjustment fitting being a projection on the fitting part and forming the inner element.
7. The vehicle seat as claimed in claim 6 wherein the third fitting part is mounted on the collar of the latching element.
8. The vehicle seat as claimed in claim 6 wherein the free-pivoting unit has a pretensioned clamping element for securing the locked pawl in the normal case and a capture element for supporting the pawl in the event of a crash.
