Abstract
A load support apparatus for a lumbar support assembly is proposed, in which reinforcing ribs are arranged on a lateral surface and a front surface of a concave portion, the load support apparatus maintaining bearing power for supporting an occupant and having a reduced weight. The load support apparatus includes a main support unit including a main plate formed in the shape of a plate, a concave portion formed by one portion of the main plate protruding backward, with a groove being formed in front of the concave portion, and a rib portion formed by protruding from the main plate toward the groove or backward from the main plate.
Claims7
A load support apparatus for a lumbar support assembly, the apparatus comprising:
- a main support unit including a main plate formed in the shape of a plate respective portions on a first side and a second side of which are formed in the shape of wings as a first-side wing portion and a second-side wing portion, a concave portion formed by one portion of the main plate protruding backward, with a groove being formed in front of the concave portion, and a rib portion formed by protruding from the main plate;
- and
- an assembly wire unit including a wire connected to the main plate in a state where opposite end portions of the wire are spaced apart in opposite directions, and extend downward;
- wherein the opposite end portions of the wire spaced apart in opposite directions form boundaries between the first-side wing portion and the second-side wing portion and the remaining part of the main plate;
- wherein the rib portion is formed only between the first-side wing portion and the second-side wing portion and only between the opposite end portions of the wire spaced apart in opposite direction;
- and
- wherein the rib portion includes traverse stiffness-enhancing ribs which are formed on portions other than the concave portions of the main plate in a manner that protrude backward from the rear surface of the main plate and front traverse stiffness-enhancing ribs which are formed in the shape of a stick in such a manner as to connect center portions of opposite-side inner lateral surfaces of a groove formed in the front surface of the main plate by the concave portion, and the front traverse stiffness-enhancing ribs are formed in the same horizontal line as the traverse stiffness-enhancing ribs and are connected to the traverse stiffness-enhancing ribs through the main plate so that the front traverse stiffness-enhancing ribs and the traverse stiffness-enhancing ribs are formed in the shape of a stick in a straight line in such a manner as to extend toward the first side or the second side.
