Infant carrier and height adjustment mechanism

A height adjustment mechanism for an infant carrier, the infant carrier comprising a carrier frame and a carrier body, wherein the height adjustment mechanism comprises:

• a positioning member,
• an elastic member,
• a release operation member,
• a fixing seat for assembling and connecting with the carrier body;
• the fixing seat is slidably arranged on the carrier frame and is slidably adjustable with respect to the carrier frame;
• and
• a sliding member slidably arranged in the fixing seat, the sliding member and the elastic member are connected in abutment manner;
• wherein the carrier frame comprises at least two positioning portions, the positioning member is movably assembled on the fixing seat and engageable with a selected one of the positioning portions;
• the release operation member is movably installed on the fixing seat, the release operation member is linked with the positioning member through the elastic member;
• during a release process in which the release operation member is operated to move, when a force of the release operation member for causing the elastic member to generate an elastic deformation is smaller than a resisting force generated by both the fixing seat and the carrier body on the fixing seat, a release movement of the positioning member is blocked and the positioning member remains engaged with the selected positioning portion;
• and
• during the release process where the release operation member is operated to move, the release operation member pushes the sliding member to slide upward and push the elastic member such that the elastic member is elastically deformed and the positioning member is disengaged from the selected positioning portion.
