Abstract: A vehicle seat assembly includes a sensor assembly that is used to provide data for an occupant classification system. The data is used to determine such characteristics as seat occupant weight and position. These characteristics are used to control deployment of a safety restraint mechanism such as an airbag. The sensor assembly is part of a mat that is placed on top of a foam cushion used to form a seat bottom. Various attachment methods can be used to permanently secure the mat to the foam cushion. Preferably, the mat includes mounting portions that are wrapped around the foam cushion to engage a bottom surface of the foam cushion. Fasteners, adhesives, hook and loop attachments, and other similar attachment members are associated with the mounting portions and are used in various combinations to secure the mat to the foam cushion.

Abstract: A solid frame orthotic seating device for use in a sling seat that is supported by solid rails, such as a wheelchair. The solid frame orthotic seating device comprises a solid, rigid, non-collapsing, and durable interior skeletal frame with an elevated anterior wedge sloping down to the top surface of the frame, lateral well support arms, and a posterior well. The frame dimensions are designed to place the user's hips into flexion, position the user's pelvis in a neutral to anterior position, and position the user's buttocks into and or below the posterior well. The anterior wedge supports and distributes the weight of the user's body away from the buttocks. The strength and design of the solid frame uniquely promotes proper positioning, and helps to anchor the user by positioning their buttocks into and or below the posterior well and or below the solid lateral well support frame.

Abstract: A seat sensor 10 including a pressure sensing mat 12, and several barbed members or tabs 14 which are integrally formed within sensing mat 12. Sensor 10 is adapted to be operatively installed on a conventional vehicle seat. In order to install sensor 10, several holes or cavities 20 are formed within the foam 22 of the seat in a conventional manner prior to assembly, and tabs 14 are forced into cavities 20. Once tabs 14 are inserted into cavities 20, barbed portions 18 “spring” outward against the sides of the cavities 20, thereby frictionally engaging and/or piercing the sides of the cavities 20 and securing seat sensor 10 to the seat.

Abstract: A wheelchair cushion having a solid gel patient interface, a matrix or honeycomb panel and a foam base. The gel layer is mold around and over the honeycomb panel to produce a composite panel with patient interface characteristics of a gel layer, but with reduced weight. The matrix panel cells are open on the lower ends which are bonded to a soft foam base. The matrix panel interacts with the foam base to spread forces and provide pressure reduction and positioning better than solid gel, but with less weight. The foam base may include several layers of differing density and contouring elements. The composite panel conforms to the base contours to provide a contoured patient interface.

Abstract: A passenger seat with low profile seat back recline locking assembly, including a recline unit for controlling movement of the seat back and locking the seat back in a desired recline position. A hydraulic cylinder assembly is pivotally-mounted by a first end thereof to a section assembly module of the seat and by an opposite second end thereof to the seat back unit. The cylinder assembly has a longitudinally-extending axis extending in alignment with the longitudinally-extending, generally vertical plane of the seat back. An actuator is positioned astride and operatively connected to the fluid cylinder adjacent one or the other of the first and second ends thereof.

Abstract: A support cushion for children's furniture defines a seat cushion area and a back cushion area and has a seating surface that extends over those areas and is contoured to provide positional support and comfort for a child seated on the cushion. The cushion preferably is a one-piece closed cell foam moulding which is flexible to permit variation in the relative angular orientation between the seat cushion and the back cushion area. The seat includes a raised transverse barrier that is spaced forwardly of the rear of the seat for controlling rotation of the pelvis of a child. The cushion further includes a pair of side support pads that extend forwardly from respectively opposite sides of the back to locate against the trunk of a child and cushion against side-to-side movement.

Abstract: The present application pertains to a seat pad particularly for motor vehicles seats, with a core portion made of expanded plastics material. The upper side of the core portion facing the seat surface is provided with channel-like grooves, so that the geometry of the remaining core portion allows an optimum distribution of the seat pressure because of the good adaptation to the human anatomy.

Abstract: Reinforcement is given in a vehicle seat with such an arrangement that a plurality of recessions and at least one decorative groove are scatteringly formed in each of two spaced-apart protuberant side support portions of the vehicle seat. A foaming is effected to create a foam padding of a predetermined shape of the seat having two spaced-apart protuberant side support portions, such as to define a plurality of first recessions and at least one first decorative groove in each of those two side support portions, after which, a trim cover assembly is pressingly bonded to the thus-formed foaming pad, thereby forcibly inserting and bonding plural points of the trim cover assembly in those first recessions and decorative groove of padding. A resulting seat is therefore provided not only with a highly enlarged area of cured and hardened adhesive layer, but also with an intensified stretched state of trim cover assembly, whereby an increased reinforcement is given to both two side support portions of the seat.

Abstract: A foam cushion suitable for use such as with a wheelchair provides a combination of general pressure relief and positioning control over legs of a patient possibly otherwise having reduced or impaired motor control skills. A desired leg position is achieved by separating the legs and supporting them in a generally parallel position. Two base pieces have predetermined upper profiles and are glued to an upper support element having integrated cubic elements for pressure relief. Channels between adjacent cubic elements facilitate flexure of the upper element to conform to the contours of the two base pieces. Relatively high ILD foam characteristics and relatively high foam densities combined with the subject structure give good results for support and for product life, including compression fatigue considerations.

Abstract: The device relates generally to a seating system and more particularly to seat cushion assemblies having a rearward depression and cushioning insert tailored to fit under the skeletal structure of the user. In particular, the assembly preferably includes an intermediate insert which fits within a base depression and a cushioning insert which can be a fluid bag, air bag, foam or gel. The insert is generally oval shaped and has a rounded bottom. This enables the cushion to be used to fit under the seating bones so as to provide a proper pelvic tilt. Further, the insert can be moved in order to provide controlled movement of the pelvis over time. A first cushioning insert is generally constructed of a material forming baffles so as to define air chambers and having a right and left seat bone area. A second design has a top and bottom so as to define the fluid envelope separated by a central baffle having apertures to allow fluid communication between the right an left portions.
