A vertically movable releasing plate has inclined surfaces so that the cross bar can be raised out of the grooves against the biasing force of a pressure plate. The cross bar is connected to a head protection plate which rotates and closes off the top of the back rest when the back rest is reclined by sliding the cross bar down the rack.

Abstract: An infant seat which converts from a car seat into a stroller. The infant seat comprises a chair connected to a wheel frame on which the wheel set is mounted. The wheel set consists of front and rear wheels connected by a linking means. When the wheel frame is in a stowed condition, it supports the chair in either a forward-facing or rearward-facing car seat configuration. The wheel set is stowed behind or below the chair while the car seat is secured to the automobile seat by the automobile safety belts threaded through the wheel frame. To convert the car seat into a stroller, the wheel frame rotates about its pinned connections to the chair to simultaneously deploy the linked front and rear wheels. The chair back reclines with respect to the chair bottom to convert the stroller into a carriage. Modifications of the wheel frame allow the infant seat to be converted into an infant rocker. Accessories such as a sun shade and footrest also extend from the chair.

To move the seat back between upright and lie-back positions it is merely necessary to release the hooks 42 from the supporting member and to swing the links 41 until the hooks 42 are engaged in the other of the support members.

Abstract: Three-point hitch structure for connecting an implement to a towing vehicle wherein the upper link is made variable by means of a hydraulic cylinder pinned to a plate to provide three pivot points. When the cylinder is retracted, the two components act as a fixed length link, with the middle pivot point maintained slightly off center with respect to the two outer pivot points by a stop member. When the cylinder is extended, the middle pivot moves away from the centerline joining the two outer pivot points to allow the overall length to either lengthen or shorten. The towed vehicle is therefore free to rock with respect to the hitch and includes gauge and stabilizing wheels to maintain the implement in proper relationship with the ground contour.

The tongue of a boat trailer is secured to the automobile trailer ahead of it by a pivot pin and a coacting tongue tie-down bar carrying two tongue radius adjusting bolts in opposing relationship to the opposite sides of the boat trailer tongue. Two tension springs are connected between the opposite sides of the boat trailer tongue and automobile trailer to assure proper tracking of the boat trailer while enabling the caravan to negotiate curves with safety.

Abstract: A bed for baby carriages which is referred to as a "box type" in the form of a unitary box, has a bottom wall (2), a front wall (3), a back wall (4), and a left-hand and right-hand side walls (5, 6). In such a boxlike bed, when the walls disposed in the front region are removed to open the front, the bed takes the form of a chair. The arrangement for making this change includes a pair of upper side frames (11) which suspend the front portions of the left-hand and right-hand side walls (5, 6). The upper side frames extend along the upper sides of the front portions of the left-hand and right-hand side walls (5, 6) and are turnably supported at their rear ends by transverse shafts.

Abstract: The disclosure relates to a means of coupling a trailer to an automobile comprising a self-aligning and shock-absorbing coupling means. The coupling means uses a fifth wheel and spring-loaded roller-detent means to maintain alignment in yaw between the vehicle and the trailer. A speed-responsive means reduces the "stiffness" in yaw between the automobile and the trailer when the vehicle speed is below a predetermined value.
