A child safety seat comprises a backrest, a seat portion connected with a lower end portion of the backrest, and a tether including a strap held with the child safety seat, and a resilient member assembled with the strap. The resilient member and the strap have different elasticity, and a tensioning of the strap causes deformation of the resilient member. When the vehicle is subject to a frontal collision or suddenly brakes, the resilient member can deform to cushion the retaining force applied by the tether, which can reduce the risk of injuries.
A child safety seat comprising:
A tether adapted for use with a child safety seat, the tether comprising a strap for being held with the child safety seat, and a resilient member connected with the strap and having a body of an elongated shape provided with first and second slots at two opposite ends, the strap passing through the first and second slots and having first and second anchor portions that are respectively adjacent to the first and second slots, an intermediate portion of the strap extending between the first and second anchor portions, the first and second anchor portions being adapted to respectively obstruct the first and second slots to prevent the strap from sliding through the first and second slots, wherein the resilient member and the strap have different elasticity, and a tensioning of the strap causes deformation of the resilient member.

1. Field of the Invention
The present invention relates to tethers used in child safety seats.
2. Description of the Related Art
FIG. 1 is a perspective view illustrating one embodiment of a child safety seat;
FIG. 2 is a schematic rear view of the child safety seat shown in FIG. 1;
FIG. 3 is a schematic bottom view of the child safety seat shown in FIG. 1;
FIG. 1 is a perspective view illustrating one embodiment of a child safety seat 100, FIG. 2 is a schematic rear view of the child safety seat 100, and FIG. 3 is a schematic bottom view of the child safety seat 100. As shown in FIGS. 1 and 2, the child safety seat 100 can include a backrest 102, a seat portion 104, and a restrain harness 106 and a tether 108. The backrest 102 and the seat portion 104 can receive the placement of a child in a seating position. The backrest 102 can have a lower end portion joined with the seat portion 104, and left and right sides respectively connected left and right armrests 110 that are located above the seat portion 104.
The restrain harness 106 can exemplary include a crotch strap 112, a pair of shoulder straps 114, a pair of waist straps 116, an adjustment strap 118 and a buckle 119. The straps 112, 114 and 116 can be made of a web material. Once the child is installed on the child safety seat 100, the straps 112, 114 and 116 can be fastened together via the buckle 119 to restrain movement of the child and hold the child with the seat in case of collision.
In one embodiment, an upper surface of the seat portion 104 can have an opening 120 through which the crotch strap 112 can be installed, such that a first end of the crotch strap 112 can be fixed with an inner side of the seat portion 104, and a second end of the crotch strap 112 can extend outward and form a free end that can fasten with the buckle 119.
