Lumbar support locking apparatus for a car seat

Abstract

A lumbar support employing a supporting member having a plurality of elastic support wings interposed between upper and lower car seat frames wherein the plurality of support wings are folded at both side end parts. A support plate having a center portion which is curved and protrudes substantially outward from the center and includes locking grooves formed at both upper and lower ends. Preferably, a support height control member is operably disposed at one side of the support plate for controlling the height of the protruded center portion of the support plate. A lumbar support locking apparatus is also provided which includes members for fixing the respective upper and lower locking grooves of the support plate in relative engagement with the locking grooves of the locking member. The lumbar support locking apparatus also includes a pair of front fixing pieces formed on opposing sides which are adapted to be inserted into engagement with the seat frames. A rear fixing piece is formed between each one of the pair of front fixing pieces by folding downward. In addition, a connecting plate is folded inward at a predetermined angle in the center portion of the locking apparatus and has a connecting groove formed at a lower part thereof, wherein the lumbar support may be fixed to the car seat without any additional brackets, and the front and rear fixing pieces fixedly engage the lumbar support in the seat frames more firmly, thereby preventing deviation of the lumbar support from the seat frames.
