A net-like structure of the present invention is one having a three-dimensional random loop bonded structure constituted of a thermoplastic elastomer continuous linear body, wherein the net-like structure has, in a thickness direction thereof, a thin fiber main region, a thick fiber main and a mixed region that is located between the thin fiber main region and the thick fiber main region and includes the thin fibers and the thick fibers in a mixed state, the fiber size of the thick fibers is greater than that of the thin fibers by greater than or equal to 0.07 mm, and the residual strain after 750 N constant load repeated compression at pressurization from the side of the thin fiber main region of the net-like structure is less than or equal to 15%.

A keyboard and keyboard and peripheral position system, which may be used with adjustable-height desks.

An infant support device for holding an infant. A fabric panel is taut between two or more anchor points. The anchor points may be disposed on a support frame or another structure capable of supporting the fabric panel and a weight of an infant. The fabric panel contains an aperture. A mesh insert is affixed to the fabric panel at the contour of the aperture. The mesh insert has a lower stiffness than the fabric panel. The mesh insert contains a plurality of holes sized to permit air to flow therethrough while preventing an infant's limbs and appendages from entering therein. Responsive to an infant being placed onto the mesh insert, the mesh insert elastically deforms thereby transitioning into a stretched configuration, in which the mesh insert urges the infant's spine into a convex curve.

A three-dimensional striped structure is provided which is formed by bonding continuous filaments in random in loops, has a longitudinal direction corresponding to an extruding direction, a lateral direction and a thickness direction perpendicular to the extruding direction, and is comprised of a polyethylene thermoplastic resin, a polyester thermoplastic elastomer or a mixture of a polyethylene thermoplastic resin and a polyethylene thermoplastic elastomer. The three dimensional striped structure has an impact resilience of not lower than 13 cm, a hysteresis loss of not higher than 34% and not lower than 13%, and a thermal expansion rate of 0 to 8% in the longitudinal direction before and after a hot-air drying test, and does not shrink during high-temperature sterilization

A portable, foldable, baby-changing table unit is provided attachable to a baby stroller for support thereby. The baby-changing table unit includes connectors for connecting the baby-changing table unit to the stroller's baby car-seat connectors. The baby-changing table unit connectors comprise foldable, transversely adjustable connection legs adapted to mate with the female receptacle connectors on the stroller normally used to releasably connect to a baby car-seat. A flexible changing pad is adapted to be attached to the portable, baby-changing table unit. The flexible changing pad includes a diaper receiver and a handy-wipe receiver. The flexible changing pad serves the dual purpose of functioning also as a carry case for the baby-changing table unit when the table is in a folded condition. An accessory connector assembly may be provided to attach the baby-changing unit to a stroller lacking a baby car-seat connector assembly.

An adjustable seat back includes a frame having a perimeter and a cushioning material that is disposed at least partially within the frame's perimeter. The adjustable seat back also includes a tension member and a plurality of straps that are disposed over the frame with a distal end that is coupled with the cushioning material and a proximal end that is operationally coupled with the tension member. A reel based tightening mechanism is operably coupled with the tension member and configured to tension the tension member and thereby tension the plurality of straps. Tensioning of the plurality of straps effects adjustment of the cushioning material.

Novel Seats having a plurality of defined zones for supporting the human anatomy are disclosed. Seats including one or more recoil shields and/or inserts to assist in supporting or isolating certain desired portions of the human anatomy, as well as seats including both seat back structures and seat pan structures, with one or both including zoned configurations designed to support and stabilize specific structures of the human anatomy in a defined manner are also disclosed. The novel seats are useful, inter alia, for individually supporting certain anatomical areas and provide seat zones that collectively support, cradle and permit the human anatomy to be supported in a comfortable manner.
