Abstract: A car seat and base with a locking mechanism are disclosed, in which the locking mechanism is mounted on the base, and a release mechanism is mounted on the car seat. The locking mechanism comprises a hooking element can be rotated to a locked position for retaining the car seat to the base, and to a release position to release the car seat from the base. The release mechanism comprises a release actuator and a plectrum follower. The release actuator is operatively mounted on the car seat, and the plectrum follower is associated with the release actuator for rotating the hooking element from the locked position to the release position, so as to permitting a user to release the car seat from the base by operating of the release actuator.

Abstract: A car seat base with a lock position indicator mechanism, includes at least two locking units, an indicating unit and an associating unit. The locking units are mounted inside the base, each has a locked position for locking a car seat thereupon, and an unlocked position that permits the car seat to be released from the base. The indicating unit provides a first color area and a second color area for indicating the positions of the locking units. The associating unit is associated between the locking units and the indicating unit; when all of the locking units have been moved to the locked position, the associating unit associates the indicating unit to reveal the first color area; and when one of the locking unit is failed to move to the locked position, the associating unit associates the indicating unit to reveal the second color area.

Abstract: A warning device for a car seat base includes a car seat base, a support leg and a color signal revealing mechanism. The car seat base is capable of mounting on a vehicle seat and provided with a support face for supporting a car seat thereupon and a signal window for showing signals by colors. The support leg is movably and rotably mounted to the car seat base. Once the length of the support leg is not yet good enough to abut the car seat base, or someday the lock means of the support leg is failed, the weight of the support leg would carry itself moving downward, by this way to cause the signal element to reveal a warning signal from signal window to the user.

Abstract: A car seat base with a self-keeping lock mechanism for releasably locking a car seat rested thereon. The car seat has a pair of rods fixed at its underside, and the self-keeping lock mechanism is characterized by including at least a front hook element and a rear hook element and at least a front positioner and a rear positioner. The front hook element and the rear hook element are spaced apart from each other and pivoted inside the car seat base for locking the rods in a closed position, and releasing the rod in an opened position; the front positioner and the rear positioner are pivoted near the hook elements for keeping the hook elements in the opened position before the rods being entered into and caught by the hook elements, and may keep the hook elements in the closed position when the rods have been locked by the hook elements.

Abstract: An adjustment mechanism for positioning a headrest in an infant car seat includes a connector, a pair of gear wheels, a ratchet wheel and a brake release handle. The adjustment mechanism is installed on the back support portion of the infant car seat which formed with a longitudinal slot and a pair of toothed guiding rails mounted in parallel on either side of the longitudinal slot. The headrest is movably connected to the back support portion by the connector to move along the longitudinal slot. The pair of gear wheels and a ratchet wheel are pivoted on the connector, the pair of gear wheels being engaged with the pair of toothed guiding rails and kept synchronized rotation with the ratchet wheel. The brake release handle is biased to releasably lock the ratchet wheel and used to unlock the ratchet wheel so as to reposition the headrest.

Abstract: An infant safety seat with an adjustable accommodating space includes a multi-layer cushioning insert which is detachably insertable into an infant safety seat for accommodating an infant in different stages of growth with different sizes. The multi-layer cushioning insert comprises a first cushioning part and a second cushioning part both may detachably to overlap each other and connect into the accommodating space to provide the necessary support for keeping an infant in proper postural position. The first cushioning part includes a U-shaped head cushion part, U-shaped body cushion part and U-shaped leg cushion part for restricting the side moving of the infant. Further, for accommodating a smaller infant, the second cushioning part can be detachably overlapped onto the first cushioning part for further reducing the side moving space and upright moving space of the baby in the infant safety seat.

Abstract: A baby stroller frame comprises a front frame, a pair of rear leg tube, and a guiding frame. The front frame connects a front wheel. The pair of rear leg tube, each has an upper end pivotally connected with the front frame, a lower end connected a rear wheel, and a joint connected with a sliding sleeve. The guiding frame has a front end pivotally connected to the front frame, and a pair of connecting arms slidably connected with the sliding sleeve. By simply rotating of the guiding frame, the sliding sleeve would carry the pair of rear leg tubes to rotate and close to the front frame. As the structure of such a stroller frame is being simplified, it would much lower the manufacture cost of a baby stroller frame and provide a new and smooth operation for a user.

Abstract: A collapsible stroller frame capable of being either collapsed or expanded with a rod set, wherein a slide sleeve is located at a front supporter of the stroller frame and a foldable supporter is pivotally connected between the front supporter and a rear supporter. A link rod connects the slide sleeve and the foldable supporter, and is pivotally connected between the front and rear supporter. The foldable supporter includes a front folding tube and a rear folding tube, pivotally connected to each other. A user can operate the foldable supporter to shorten the distance between the front and rear folding tubes, by disengaging the slide sleeve from the frame, thereby facilitating assembly and folding of the stroller.

Abstract: A wheel assembly for baby stroller has its rotating shaft rod on a central axis along which the shock absorbing compression spring moves. In this way, the wheel assembly is not only capable of having shock absorbing function by making use of the compression spring but is also capable of being not affecting the rotating effect of the wheel assembly.

Abstract: A release mechanism for stroller includes a seat portion comprising a pair of positioning bars disposed transversely for fixedly locking two sides of frame of baby stroller so as to extend the frame in an expanded position. A handle grip is disposed between the pair of positioning bars, wherein the handle grip forces the positioning bars to disengage from two sides of the frame so that the stroller can be folded in a collapsed position. A user has to carry the baby outside of the seat portion before folding the frame since the handle grip is arranged at the seat portion of baby stroller. The structure of the present invention has the advantages of not only folding the stroller by a single hand but avoiding the dangers which might be caused if the user accidentally and inadvertently folds the stroller upon operating.
