Abstract: A pad assembly is described that retains a blade assembly or set to the body of a hair cutter. The pad assembly reduces random forces generated by the blade assembly and ensures an accurate and repeatable tension is maintained between the inner and outer blades of the blade assembly. The pad assembly acts as an intermediary between the blade assembly and the body of the hair clippers to reduce challenges associated with fasteners directly attaching the blade assembly to the body of the clipper.

Abstract: A blade assembly for a hair cutting apparatus includes a first blade having teeth extending along a first blade edge, and a second blade having teeth extending along a second blade edge. A distance between the first and second blade edges defines a blade gap. A yoke is coupled to the second blade and configured to convert motion of a drive into reciprocation of the second blade relative to the first blade to cut hair. A spring includes a spring base and at least one spring arm configured to reciprocate with the second blade. A guide assembly includes a guide and a spring retainer, the guide being positioned between the first blade and the second blade, and the spring retainer fixing the spring base relative to the first blade, wherein in response to moving the guide relative to the first blade, the blade gap changes.

Abstract: A hair grooming device includes a body having a lower housing and a removable cover, the lower housing defining a substantially hollow cavity. The lower housing is formed of a first material. A liner is received by the lower housing in the cavity. The liner is formed of a second material, the second material is different than the first material.

Abstract: A drive for a hair trimmer include a transmission having a cam follower coupled to a drive lever by a bridge member, and a hinge having a mounting structure coupled to a first end of a plurality of webs, and a cross-bar coupled to a second end of the plurality of webs. A portion of the cross-bar encloses the bridge member to connect the transmission and the hinge.

Abstract: A drive assembly for a hair grooming device includes a yoke assembly and a support assembly. The yoke assembly includes a slot that is configured to receive an eccentric drive, and a biased tension arm having a finger at one end, the tension arm configured to engage a blade assembly. The support assembly is coupled to the yoke assembly, the support assembly includes a first arm spaced apart from a second arm, the first and second arms being respectively coupled to the yoke assembly, the yoke assembly being positioned between the first and second arms.
