- a child seat having a seat support upon which the child may sit and back support against which the child may rest;
at least one coupling, said coupling including;
(a) a frame, said frame having a proximal end and a distal end, the distal end of said frame having a notch with a mouth and a seat that is adapted to receive the fixedly mounted rigid member;
(b) a lever with a finger mounted on its distal end;
said lever pivotally mounted on said frame with the distal end of said lever extending beyond the seat of the notch in said flame;
wherein said lever has a closed position wherein said finger substantially covers the mouth of said notch and an open position wherein said finger is substantially removed from the mouth of said notch;
(c) means for biasing said lever toward the closed position;
(d) means for securing said coupling to said child seat;
whereby the coupling of the child restraining device may be releasably engaged with the fixedly mounted rigid member of the passenger seat of a vehicle by (i) pushing the fixedly mounted rigid member into the notch in the frame of said coupling, (ii) moving the lever in an open position until the fixedly mounted rigid member is proximal to the finger on said lever, and (iii) allowing said lever to return to its closed position;
(e) a button operatively connected to the proximal end of said lever, whereby pushing said button, said finger is substantially lifted out of the mouth of said notch; and
(f) said frame also including a housing and two stationary plates mounted inside said housing on ieach side of said lever.

Abstract
A coupling and web adjuster to attach an infant seat to the passenger seat of a vehicle having a fixedly mounted rigid member to which the seat may be attached. The web adjuster has a cylindrical bar with a generally oval cross-section and a pair of ears mounted near each of its ends; a web that extends at least partially around the bar, a frame with a pair of channels in which the ears of the bar may slide, and one or more mechanical springs to normally push the bar toward the web stop and against the web. One version of the coupling is characterized by a frame having a notch on its distal end with a mouth/seat that is adapted to receive the fixedly mounted rigid member and a lever that is pivotally mounted inside the frame to hold the rigid member inside the mouth. The lever has a downwardly projecting finger that blocks the mouth of the notch when moved in one direction and allows access to the notch when moved in the other direction. Another version of the coupling is characterized by a rigid hollow cylinder with two notches in one end, a piston that slides back and forth inside the cylinder, a spring to push the piston toward the notches; and a means to prevent the piston from sliding out of the cylinder. Either coupling may then incorporate the first described web adjuster to attach the coupling to the child seat.

1. A child restraining device for mounting in the passenger seat of a vehicle having at least one fixedly mounted rigid member, comprising:
-
a child seat having a seat support upon which the child may sit and back support against which the child may rest;
at least one coupling, said coupling including;
(a) a frame, said frame having a proximal end and a distal end, the distal end of said frame having a notch with a mouth and a seat that is adapted to receive the fixedly mounted rigid member;
(b) a lever with a finger mounted on its distal end;
said lever pivotally mounted on said frame with the distal end of said lever extending beyond the seat of the notch in said flame;
wherein said lever has a closed position wherein said finger substantially covers the mouth of said notch and an open position wherein said finger is substantially removed from the mouth of said notch;
(c) means for biasing said lever toward the closed position;
(d) means for securing said coupling to said child seat;
whereby the coupling of the child restraining device may be releasably engaged with the fixedly mounted rigid member of the passenger seat of a vehicle by (i) pushing the fixedly mounted rigid member into the notch in the frame of said coupling, (ii) moving the lever in an open position until the fixedly mounted rigid member is proximal to the finger on said lever, and (iii) allowing said lever to return to its closed position;
(e) a button operatively connected to the proximal end of said lever, whereby pushing said button, said finger is substantially lifted out of the mouth of said notch; and
(f) said frame also including a housing and two stationary plates mounted inside said housing on ieach side of said lever. - View Dependent Claims (2, 3)

4. A child restraining device for mounting in the passenger seat of a vehicle having at least one fixedly mounted rigid member, comprising:
-
a child seat having a seat support upon which the child may sit and back support against which the child may rest;
at least one coupling, said coupling including;
(a) a frame, said frame having a proximal end and a distal end, the distal end of said frame having a notch with a mouth and a seat that is adapted to receive the fixedly mounted rigid member;
(b) a lever with a finger mounted on its distal end;
said lever pivotally mounted on said frame with the distal end of said lever extending beyond the seat of the notch in said frame;
wherein said lever has a closed position wherein said finger substantially covers the mouth of said notch and an open position wherein said finger is substantially removed from the mouth of said notch;
(c) means for biasing said lever toward the closed position; and
(d) means for securing said coupling to said child seat;
whereby the coupling of the child restraining device May be releasably engaged with the fixedly mounted rigid member of the passenger seat of a vehicle by (i) pushing the fixedly mounted rigid member into the notch in the frame of said coupling, (ii) moving the lever in an open position until the fixedly mounted rigid member is proximal to the finger on said lever, and (iii) allowing said lever to return to its closed position;
wherein the means for securing said coupling to said child seat includes a web adjuster, said web adjuster further comprising;
a bar with a frontal plane, a longitudinal axis, a front face, and a back face, said bar including a pair of ears mounted near the opposite ends of said bar, said ears further mounted crosswise to the longitudinal axis of said bar;
a web extending at least partially around said bar;
a frame with a pair of channels with the ears of said bar slidably mounted in said channels, said frame also including a web stop extending parallel to said bar; and
means for urging the front face of said bar against said web and toward said web stop. - View Dependent Claims (5, 6, 7, 8, 9, 10)
