Abstract: Crosslinkable polymers, such as dendritic macromolecules and their in vitro, in vivo, and in situ uses are disclosed. These biomaterials/polymers are likely to be an effective sealant/glue for a variety of surgical procedures where the site of the wound is not easily accessible or when sutureless surgery is desirable. Crosslinkable dendritic macromolecules can be fabricated into cell scaffold/gel/matrix of specified shapes and sizes using chemical techniques. The polymers, after being crosslinked, can be seeded with cells and then used to repair or replace organs, tissue, or bones. Alternatively, the polymers and cells can be mixed and then injected into the in vivo site and crosslinked in situ for organ, tissue, or bone repair or replacement. The crosslinked polymers provide three dimensional templates for new cell growth that is suitable for a variety of reconstructive procedures, including custom molding of cell implants to reconstruct three dimensional tissue defects.

Abstract: A car seat is constructed to be adaptable for use by children within the toddler-size range and the youth-size range. In particular, the car seat includes cam-shaped arm rests which can be rotated about an axis roughly parallel to a seat bottom, with the rotation resulting in supporting surfaces at different heights relative to the seat bottom. In addition, the car seat has a base portion which allows a seat body to be reclined relative to the base portion, and a five-point harness which is easily removed or adjusted for children of varying heights. The car seat also has a moveable or removable head support. The car seat can be adjusted for children of varying heights and weights, avoiding the costs of multiple car seats for different sized children.

Abstract: An infant carrier assembly and a method controlling an infant carrier position use a base and a movable trolley mounted to a vehicle in a rearwardly facing direction. An infant carrier is detachably mounted to the trolley. The trolley is movable so that the carrier is movable between two reclined positions, 58° and 49° from the vertical to the infant carrier seatback. A sacrificial link and springs connect the trolley to the base to limit the movement between the two positions. During a front collision, e.g., when 1 or more G-force is created, the sacrificial link breaks away to release the trolley/carrier from the reclined positions to an upright position, where the carrier seatback can be upright up to about 15% (14°) from the vertical.

Abstract: A web adjuster for securing a web and a seat including the web adjuster. The web extends through the web adjuster including a mounting plate that is mounted to the seat. A sliding plate moves relative to the mounting plate for lockingly engaging the web. Resilient biasing elements bias the sliding plate into locking engagement, and a release handle displaces the sliding plate against the resilient biasing elements.

Abstract: A playyard (10) includes a floor (12) and side panels (20) extending upwardly from the floor to provide an enclosure. At least one of the side panels has an opening (26) therethrough which is selectively covered by a pivotal door panel (30) to preclude access to and from the enclosure. The door panel (30) has a pair of retractable, spring-biased tube assemblies (40) that engage corners (16) which interconnect rails (18) that support the side panels.

Abstract: An adjustment mechanism for a car seat provides multiple vertical locking positions for adjusting the attitude of a seat with respect to an automobile seat cushion and back. The car seat has a base with forward and rear support walls each having a key way matching the profile of the stem portion of a locking plunger. The plunger has a forward handle portion and a pair of shoulder portions extending to the rear of the plunger which engage mating recesses in a key way formed in an adjustable support member. The adjustable support member is slidably arranged between the forward and rear support walls of the base. The plunger is spring biased by a spring mounted in a spring aperture formed in the rear of the plunger stem.

Abstract: A removable latching assembly for use with a child's stroller. The stroller has a latch support post with a latch lug and a bearing surface, and a pivot support post with a bearing surface. The latching assembly includes a latching portion having an engagement surface and a manually operable latch lever with a pawl engagable with the latch lug, and a pivot portion with a bearing surface slidably engagable with the bearing surface of the pivot support post. To install, the pivot portion is maneuvered onto the pivot post bearing surface, the assembly is rotated by substantially ninety degrees about the bearing surface of the pivot support post until the latching portion engagement surface encounters the bearing surface of the latch support post. The latch lever is manipulated to engage the latching pawl with the latch lug.
