Abstract

A reclining seat has a seat cushion and a seat back pivotally mounted on the seat cushion. A locking structure for the reclining seat include first and second brackets fixed to the seat cushion and the seat back, respectively. The locking structure also includes two arcuated guide members formed on the first bracket and an internally-toothed gear formed on the second bracket. The two guide members are received in a recess formed inside the internally-toothed gear, and two lock gears and a cam for moving them in opposite directions are interposed between the two guide members. Each lock gear has a pawl engageable with the internally-toothed gear. Each guide member has a guide recess defined therein and positioned away from the cam, and the associated lock gear is slidably received in the guide recess.
