Definitions

  • This invention relates to an infant car seat including a foldable handle that may be rotated between a carrying position (in which an infant in the car seat may be carried) and a storage position (in which access to a seating area in the car seat is facilitated).
  • Rear-facing infant car seats generally include a base that can be secured to a vehicle seat and an infant carrier detachably coupled to the base.
  • the infant carrier has a carrying handle so that a parent can carry a sleeping child from car to home without disturbing the child.
  • the infant carrier also can be snapped onto a stroller to make a travel system.
  • the infant carrier can play an important part in daily parental care of a child, and ease of use of the infant carrier is critical to parents.
  • Carriers with handles generally have a handle lock on each side of the carrier, both of which must be released to rotate the handle away from the child seating area. Oftentimes, the handle is left in the up (or carrying) position.
  • the parent goes to place the child in the carrier, the parent cannot simultaneously manipulate the handle and hold the child. Instead, the parent must set the child down, away from the carrier, then use both hands to unlock and rotate the handle away from the child seating area, and finally lift and place the child in the carrier. This sequence can be awkward, frustrating, and time- consuming for the parent.
  • An embodiment of the present invention relates to a carrier configured to be secured to a base of an infant seat.
  • This carrier includes, among other possible things: a seat shell including an infant seating area and first and second handle mounts on opposite sides of the infant seating area; a handle rotatably coupled to the seat shell such that first and second ends of the handle are mounted to the first and second handle mounts, respectively; first and second locking mechanisms associated with the first and second ends of the handle, respectively, the first and second locking mechanisms being configured to lock the handle relative to the seat shell; and an actuator mounted to the, handle, the actuator being configured to unlock the first and second locking mechanisms solely by moving the actuator from a locked position to an unlocked position relative to the handle.

Abstract

La présente invention a trait à un porte-bébé (100) comprenant un corps de siège (120) et une poignée (110). La poignée peut être déplacée entre une position de portage et une position de rangement par l'actionnement, avec une seule main, d'un ensemble d'actionnement (800) prévu dans la poignée. Lors de son actionnement, un actionneur de l'ensemble d'actionnement libère les mécanismes de verrouillage (200) associés aux première et deuxième extrémités (118) de la poignée où la poignée est assemblée au corps de siège. La libération des mécanismes de verrouillage permet la rotation de la poignée par rapport au corps de siège.
