International Classification:

F16M013/00

US Classification:

29734415, 29734412, 248550, 248564, 248577

Abstract:

A suspension for a seat that varies the preload, spring rate and damping rate of the suspension in direct proportion to the suspended weight of an occupant of the seat to provide the same effective vibration isolation for any occupant. The suspension includes an actuating mechanism engaged with a first spring and a pivotal transfer link that is engaged with a second spring and a non-adjustable rate damper that are each fixedly attached to the seat opposite the transfer link. The transfer link is engaged with a weight adjustment mechanism which operates to adjust the position of a pivot pin for the transfer link with respect to the transfer link, such that the preload, spring rate and damping rate of the suspension are adjusted in proportion to the weight of the occupant of the seat to provide similar ride dynamics to any occupant of the seat.

John Kucharski - Brown Deer WI, US
Kevin E. Hill - Mequon WI, US

International Classification:

B60N 2/14

US Classification:

29734424

Abstract:

A swivel mechanism for a vehicle seat that includes a plurality of pairs of plates that are rotatively coupled providing a first stage of movement where the seat and at least one plate rotates while displacing out of the way of an obstacle and a second stage where the seat and at least one plate rotates without displacing. In an embodiment, a base plate that remains fixed in a home position while a coupling plate and seat-supporting plate rotate about a first pivot offset from the center of the base plate during the first stage and the seat-supporting plate rotates about a second pivot disposed in a center of the coupling plate during the second stage. The coupling plate is slidably coupled to the base plate and to the seat-supporting plate with at least one guide pin and slot arrangement limiting relative movement during the first and second stages.

International Classification:

US Classification:

156213

Abstract:

A method of making a seat (10) includes preassembling the seat by positioning a seat cover (26) over a contoured foam substrate (18) with a layer of heat activated adhesive (24) between the seat cover and the foam substrate. Securing the seat preassembly (10') in a fixture (106) and introducing heating fluid into the fixture to pressurize a flexible bladder (156) against the seat. The pressurized bladder urges the seat cover against the contoured foam substrate and heats the adhesive layer. Next, cooling fluid is introduced into the fixture to pressurize the flexible bladder against the seat, and the pressurized bladder urges the seat cover against the contoured foam substrate and cools the adhesive layer.
