Definitions

  • the present invention relates to child safety seats.
  • an automobile vehicle has seatbelts provided at the front and rear seats.
  • the seatbelt generally includes shoulder and lap straps that may be fastened with an anchor point of the vehicle to restrain and protect the occupant in case of collision or sudden stop of the vehicle.
  • the use of the vehicle seatbelt is not adapted for a young child who has a smaller body and may not be able to sustain the pressure applied by the seatbelt.
  • safety legislations require the use of a child safety seat for seating a young child in a vehicle.
  • the seatbelt of the vehicle can be used to hold the child safety seat in place.
  • the child safety seat can be provided with an independent restraint system that can attach with an anchor structure of the vehicle to hold the child safety seat in place.
  • the child safety seat can also be installed in the vehicle in a position facing forward or a position facing rearward. Each of these two positions requires a different procedure for securing the child safety seat, which may be subject to confusion and erroneous manipulation from the caregiver.
  • the present application describes a child safety seat that is provided with a restraint system for attaching the child safety seat in a vehicle.
  • the child safety seat includes a seat shell having one side provided with an elongated slot, and an anchor strap portion restrictedly held with the seat shell.
  • the slot communicates with a first opening near a front of the seat shell, and a second opening near a rear of the seat shell.
  • the anchor strap portion is connected with a fastener that is operable to attach with an anchor structure provided in a vehicle, the anchor strap portion being movable along the slot between a first position adjacent to the first opening, and a second position adjacent to the second opening.
  • At least one advantage of the structures described herein is the ability to conveniently adjust the positions of the anchor strap portions by pulling the strap portions along the seat shell toward its front or rear. Accordingly, the installation of the child safety seat in a vehicle can be facilitated, and erroneous manipulation can be prevented.
