1. Apparatus for locking an infant carrier into a base which is mountable to a car seat, said apparatus comprising:

  • a bolt slidably mounted to said base and spring-biased to project laterally therefrom said bolt having a sloping surface oriented to yield under a transverse contact force and thereby cause retraction of said bolt;

    a hollow in said carrier to receive said bolt, said hollow having a rim capable of exerting said transverse contact force to said sloping surface of said bolt during insertion of said carrier into said base;

    a projection extending transversely from said bolt; and

    a lever arm mounted to said carrier, said lever arm having a cam protruding radially from the fulcrum thereof to engage said projection when said carrier is inserted into said base, said cam being spiraled to urge said projection backward and thereby retract said bolt upon turning of said lever arm.
