• the present invention relates to a structural part and a vehicle seat with a backrest.
• the present invention is therefore based on the object, a structural part, in particular for a backrest of a vehicle seat, or a vehicle seat with a backrest, in particular for a rear seat of a vehicle to specify such that a reinforcing element, in particular for receiving belt forces considerably easier and thus can also be carried out more cost-effectively and yet a high degree of safety for the occupants of the motor vehicle is guaranteed.
• a structural part in particular for the backrest of a vehicle seat, wherein the structural part has at least one plate element and further comprising at least a first profile element and a second profile element and extending substantially along the edge of the plate member reinforcing frame, wherein at least partially within a reinforcing element is provided in the plane of the reinforcing frame and further wherein the reinforcing element is provided only with the first profiled element and with the
• BEST ⁇ TIGUNGSKOPHr Plate element is connected.
• a particular advantage results according to the invention in that a particularly simple and fast production of the structural part is possible by a connection only to one of the profile elements forming the frame.

• the reinforcing element is very particularly preferred for the reinforcing element to be provided for connecting a belt retractor of a safety belt, wherein a belt deflecting device assigned to the belt retractor is provided on the first profile element and / or on the reinforcing element, or it is preferred that the reinforcing element be in the area of the first profile element extends over 30% to 80% of the extent of the first profile element, preferably over 40% to 70% of the extent of the first profile element, more preferably over 45% to 65% of the extent of the first profile element, most preferably over 50% to 60% of the extension of the first profile element.
• the first and / or second profile element is at least partially connected to the plate element by means of butt welding.
• a leg of one of the profile elements with its (along the profile part extending) edge (which essentially only the surface of the material thickness multiplied by the length of the edges) is connected to the surface of the plate member by means of welding.
• this type of welding takes place by means of a laser (laser welding), wherein the laser beam is from the side of the plate element facing away from the (just to be welded) profile element.
• the reinforcing element is preferably connected by means of laser welding to the plate element and / or the reinforcing frame.
• the first and / or second profile element is provided as a U-profile and / or a C-profile and / or a Z-profile, wherein in cross-section the leg end or the leg ends of the first and / or second profile element are preferably provided without fastening straps.
• the first and / or second profile element may (also) have tabs.
• the first and / or second profile element has a shape or a cross-section such that, after the connection to the plate element, a hollow profile having a comparatively high stability is formed.
• U-profiles or C-profiles which have an open side in cross-section, which is closed by the connection to the plate element to form a hollow profile
• the first and / or the second profile element is designed as an L-profile or as a Z-profile.
• a hollow profile can also be produced with such a profile element (after assembly).
• the profile elements together form either a closed (in particular substantially rectangular or rectangular) reinforcing frame or even form a U-shaped arrangement on the plate member.
• a completely closed frame it is inventively provided in particular that four profile elements (the first and second profile element together with a third and a fourth profile element) are provided, each profile element on the one hand with the plate member and each profile element to the other with two other Profile elements are connected to form the frame.
• more than four profile elements are used to complete the frame;
• corner pieces or corner profile elements are provided in the corner regions of the frame.
• Figure 1 shows schematically a side view of a vehicle seat with a backrest.
• FIGS. 2 and 5 each schematically show a structural part according to the invention, for example for use in the backrest of a vehicle seat.
• Figures 3 and 6 show schematically each a reinforcing element in a perspective view.
• FIG. 4 shows schematically a structural part known from the prior art.
• FIG. 1 is a schematic side view of a vehicle seat 10 according to the invention with a backrest 20 and a seat part 15.

• the profile elements 41, 42, 43, 44 are welded together in particular in corner regions of the reinforcing frame 40. Further, the profile elements 41, 42, 43, 44 with the plate member 30th welded.
• a reinforcing element 50 is provided.
• the reinforcing element 50 serves, in particular, to absorb forces that originate from a belt retractor or act between a belt retractor and a belt deflecting device.
• the connection point or the connection location for a belt retractor is designated by the reference numeral 56 in FIG. 2 and FIG.
• the Gurtumlenk liked is designated by the reference numeral 55.
• the forces introduced by the reinforcing element, in particular into the reinforcing frame 40 are distributed over a comparatively large area (spatially), so that a load-bearing capacity (in comparison to the weight of the reinforcing element 50) of the overall arrangement results.
• relatively small material thicknesses can be used in the reinforcing element 50. This results in a relatively large change in shape in the load case (especially in the accident situation). Due to the relatively large change in shape, in turn, a larger portion of the load to be absorbed is received via the plate member 30 and thus also introduced more uniformly in the reinforcing frame 40.
• the Gurtumlenk issued 55 and the attachment point 56 for a belt retractor also a tether 57 for a side lock (in particular for fastening or locking the backrest 20 on a vehicle chassis or the vehicle body) and in Figure 2 an axis of rotation 58 (in particular for realizing a pivotability of the backrest 20 relative to the vehicle body (for example for producing a larger boot volume)).
