Patent ID: 7210646

Claim:
A cord seat assembly comprising: a seat comprising an end wall, the seat further comprising a through-hole in a bottom thereof; a spool rotatably supported by the seat, the spool including a first end and a second end; and a cord extending through the through-hole of the seat, the cord being wound around the spool and including an end fixed to the first end of the spool, the cord being movable along a retrievable direction and a releasing direction; the end wall of the seat comprising a lateral extension wall extending from a side of the end wall along a lateral side of the seat, the lateral extension wall being adjacent to the through-hole and including a guiding face facing the second end of the spool; wherein the cord that has passed through the through-hole abuts against and is guided by the guiding face onto the spool when the spool is turned in the retrieving direction of the cord; wherein the end wall of the seat comprises another lateral extension wall extending from another side of the end wall opposite to the side of the end wall along another lateral side of the seat opposite to the lateral side of the seat, said another lateral extension wall guiding the cord that has passed through the through-hole onto the spool when the spool is turned in the retrieving direction of the cord, wherein an axial distance between a relatively upper point on the guiding face of said another lateral extension wall and the through-hole is smaller than that between a relatively lower point on the guiding face on said another lateral extension wall and the through-hole.
