The ratchet wheel (3) comprises a base plate (A), the base plate (A) is provided with a stamping groove (a), ratchet wheel ratchets (3a) are arranged on the peripheral wall of the stamping groove (a), and the depth of the ratchet wheel ratchets (3a) is larger than the thickness of the base plate (A). The invention further provides a seat angle adjuster. The ratchet wheel is formed by punching the base plate (A), the depth of the ratchet teeth (3a) of the ratchet wheel is larger than the thickness of the base plate (A), compared with the prior art, the thickness of the base plate (A) is reduced, the weight of the base plate (A) is reduced, the weight and the thickness of the angle adjuster are reduced, and the requirement for light weight is met.

    本发明公开一种用于座椅调角器的棘轮,所述棘轮(3)包括基板(A),所述基板(A)具有冲压槽(a),所述冲压槽(a)的周壁设置有棘轮棘齿(3a),所述棘轮棘齿(3a)的深度大于所述基板(A)的厚度。本发明还提供一种座椅调角器。本发明棘轮由基板(A)冲压成型,并设置棘轮棘齿(3a)的深度大于基板(A)的厚度,与现有技术相比,基板(A)厚度减薄,重量减轻,进而降低调角器的重量和厚度,满足轻量化要求。
