Backrest part for a seat, in particular a vehicle seat
View Patent ↗A backrest part for a seat, in particular a vehicle seat, includes at least one back metal sheet and individual profiled elements. The back metal sheet has beadings which protrude in the direction of the profiled elements in some sections. The profiled elements are connected to the back metal sheet in a force-fitting and/or bonded manner in a region of the beadings. A section with beadings is formed in each corner of the back metal sheet. The beadings of each section are arranged in parallel at a specifiable distance to one another. The beadings of each section extend diagonally between the adjoining edges of the back metal sheet. The beadings of mutually adjacent sections run at an angle relative to one another. The length of the beadings running parallel to one another in each section decreases in the direction of the corners.
1. A backrest part for a seat, comprising:
at least one back plate; and
a plurality of individual profiles,
wherein the back plate has beadings protruding in sections in a direction of the profiles, and the profiles are connected in at least one of a frictional and integrally bonded manner to the back plate in a region of the beadings,
wherein the sections having a plurality of beadings are formed in each corner of the back plate,
wherein the beadings of each section are in each case arranged parallel to each other at a predetermined distance,
wherein the beadings of each section in each case extend diagonally between adjacent edges of the back plate,
wherein beadings of mutually adjacent sections run at an angle relative to one another, and
wherein a length of the beadings running parallel to one another decreases in the respective section in a direction of the corners.
2. The backrest part as claimed in claim 1 , wherein at least one junction plate is arranged in a region of two mutually adjacent profiles on surface sides thereof opposite the protruding beadings of the back plate and is connected to the respective profiles in at least one of a form-fitting, integrally bonded, and frictional manner.
3. The backrest part as claimed in claim 1 , wherein the profiles are arranged in an encircling manner on the back plate such that a profile frame is formed.
4. The backrest part as claimed in claim 1 , wherein adjacent profiles are arranged on the back plate in a manner overlapping on an end side.
5. The backrest part as claimed in claim 1 , wherein the profiles have an open or a closed cross section.
6. The backrest part as claimed in claim 1 , wherein the beadings are of trough-shaped or channel-shaped design.
7. The backrest part as claimed in claim 6 , wherein a cross section of the beadings is of trapezoidal, rectangular, square or rounded design or of rounded design with flattened portions.
