A method for making a seat includes the step of overmolding a carrier onto a fabric seat surface. The fabric surface is formed from a woven fabric material having heating element fibers. The heating element fibers are placed in contact with a conductor. The carrier and the conductor are then positioned into a frame.

A load bearing surface includes a woven fabric surface and a carrier () overmolded onto the fabric surface. Portions of the woven fabric are bonded to the carriers () o as to remain fixed relative to the carrier during normal loading conditions and during abnormally high loading conditions. Other portions () of the woven fabric are bonded to the carrier so as to remain fixed relative to the carrier during normal loading conditions and to move or slip within the carrier, or to rupture, during abnormally high loading conditions.

Load bearing surface with kinetic energy management fabric

A seat includes a seat surface having a periphery and a carrier overmolded onto the seat surface over the periphery. The carrier has a periphery and a frame is overmolded onto the carrier over the carrier periphery. The seat is assembled without fasteners. A method for making the seat includes overmolding a carrier onto a periphery of a seat surface to form a seat surface/carrier assembly, tensioning the seat surface/carrier assembly in a mold and overmolding a frame onto a periphery of the seat surface/carrier assembly.

Suspension seating surface edge encapsulation method, seating surface carrier and seat made therewith

A suspended fabric seat includes a frame, a woven fabric suspended in the frame and a plurality of compression limiters attached to the woven fabric. The woven fabric is formed from monofilament fibers that are oriented in a first direction and textile fibers oriented in a second direction transverse to the first direction. The plurality of compression limiters are oriented in the first direction and are formed from a material compatible with the woven fabric. A method for making the suspended fabric seat is also disclosed.

Seat comprising suspension fabric with compression limiters

A seat and cooling system for the seat include a porous seat surface, an air spacer disposed on a side of the seat surface that defines an air channel, a substantially air impermeable barrier having an opening therein in communication with the air channel and a blower configured to draw air through the seat surface and from the air channel. Air drawn from around an occupant on the seat surface draws moisture from the occupant, causing moisture to evaporate, to provide a cooling sensation.

A suspension fabric seat includes a fabric seat surface formed from a woven fabric material having heating element fibers. The heating element fibers are in electrical communication with a conductor. A carrier is overmolded onto the seat surface. The carrier and the conductor are disposed in a frame and a connector is mounted to the frame in electrical communication with the conductor.

A system for hiding flash in a suspension seat includes a frame having a channel having at least one wall, a fabric seat surface and a carrier over-molded onto the seat surface. The carrier has a wall and is over-molded onto the seat surface such that the seat surface extends from the wall. The carrier and a portion of the seat surface at a juncture of the carrier and the seat surface are positioned in the channel with the portion of the seat surface abutting the wall of the channel, such that flash formed at the juncture of the carrier and the seat surface is positioned against the wall of the channel. A seat formed thereby and a method for making the seat are disclosed.

System and method for hiding molding flash

An apparatus and method for molding a component onto a stretched blank. The apparatus includes a stretching assembly mounted adjacent to a first mold part. The stretching assembly includes a plurality of clamp assemblies that grasp the peripheral edge of the blank and a plurality of slide assemblies that move the clamp assemblies away from one another to apply a stretch to the fabric. The apparatus further includes a press for closing a second mold part onto the first mold part while the fabric is held in a stretched condition by the stretching assembly. In one embodiment, the stretching assembly may include a float plate that is movable with respect to the first mold part between a stretch position and a mold position. The apparatus may include a robot with tooling for moving the fabric onto the stretching assembly. The tooling may include a plurality of shot pins that push the fabric off of the tooling onto corresponding fabric pins in the stretching machine.

In one embodiment, the apparatus include a stretch measuring device adapted to measure the stretch applied to the fabric.

A chair includes a control housing, a seat and a back support including an upwardly extending upright portion and a link portion extending forwardly from a lower portion of the upright portion. The link portion is pivotally connected to the control housing about a first pivot axis. The seat is connected to the link portion and is pivotable relative thereto. A linkage is coupled to the seat and is pivotally connected to the control housing at a second pivot axis positioned rearwardly and downwardly from the first pivot axis.

Contoured seating structure

A seating structure includes a backrest having a top and bottom and includes a frame. The frame includes a pair of spaced apart side members defining an opening therebetween. Each of the side members has a length. A flexible membrane extends between and is attached to the side members across the opening. An armrest is moveably mounted to each of the side members. Each of the armrests is adjustably moveable along at least a portion of the length of the side members between at least a first position and a second position. The first position is closer to the bottom of the backrest than the second position. A method of adjusting the seating structure is also provided.

A seating structure includes a support structure, a seat supported by the support structure and a backrest pivotally connected to the support structure. The seat includes a front and rear. The backrest is positioned adjacent the rear of the seat. The backrest includes a frame having a pair of bow-shaped side members. Each of the side members has a lower section and an upper section. The upper sections extend from the lower sections so as to form a pair of first bowed sections at substantially a lumbar region of the backrest. A flexible membrane is attached to and extends between the side members. The flexible membrane has a second bowed section corresponding to the first bowed sections of the side members. A method of using the seating structure is also provided.

A seating structure includes a support assembly for supporting the body of a user. The support assembly includes a frame member defining an opening and having a channel formed around at least a portion of a perimeter of the opening and an expandable carrier member expandable between at least a first and second configuration. The carrier member is inserted into the channel when expanded to the second configuration. A membrane of elastic material covers the central opening. The membrane has an edge, at least a portion of which is attached to the carrier member. The membrane is stretched a desired amount as the carrier member is expanded between the first and second configurations. A method of assembling a seating structure is also provided.
