Vehicle seating assembly with displaceable platform

Abstract

A vehicle seating assembly having a seat cushion and a suspension system disposed proximate an underside of the seat cushion. The suspension system includes a carrier assembly, a displaceable platform, and an attachment member extending between the carrier assembly and the displaceable platform, wherein the attachment member is positionable between the rest position and an extended position. The displaceable platform is positionable between a design position and a fully deployed position.

         5 . The vehicle seating assembly of  claim 4 , wherein the pitch plate is in a primary position when the displaceable platform is in the design position and wherein the pitch plate is in a secondary position when the displaceable platform is in the fully deployed position. 
     
     
         6 . The vehicle seating assembly of  claim 5 , wherein the primary position is a lowered position and wherein the secondary position is a raised position. 
     
     
         7 . The vehicle seating assembly of  claim 6 , wherein the carrier assembly includes a carrier having four segments. 
     
     
         8 . The vehicle seating assembly of  claim 7 , wherein the four segments include first and second opposing segments positioned longitudinally along a seat and third and fourth segments positioned laterally across the seat. 
     
     
         9 . The vehicle seating assembly of  claim 8 , wherein the attachment member is coupled to the fourth segment. 
     
     
         10 . The vehicle seating assembly of  claim 9 , wherein the pitch plate is coupled to the third segment. 
     
     
         11 . The vehicle seating assembly of  claim 10 , wherein the pitch plate includes first and second attachment members extending from the pitch plate and wherein the first and second attachment members are coupled to the third segment. 
     
     
         12 . The vehicle seating assembly of  claim 11 , wherein the first and second attachment members are rotationally coupled to the third segment. 
     
     
         13 . The vehicle seating assembly of  claim 7 , wherein the carrier assembly
 includes a panel disposed in the carrier.   
     
     
         14 . The vehicle seating assembly of  claim 13 , wherein the T-shaped link extends through a slot in the panel. 
     
     
         15 . A vehicle seat comprising:
 front and rear portions;   a displaceable platform disposed on a carrier assembly, wherein the displaceable platform is movable between a design position and a fully deployed position; and   an attachment member pivotably coupled to the carrier assembly and including:   a T-shaped link coupled to the displaceable platform, wherein the displaceable platform is disposed proximate a rear portion of the carrier assembly in the design position, wherein the displaceable platform is disposed proximate a front portion of the carrier assembly in the fully deployed position, and wherein the displaceable platform is pivotably coupled to the front portion of the carrier assembly and slidably coupled to the rear portion of the carrier assembly.   
     
     
         16 . The vehicle seat of  claim 15 , wherein the attachment member is positionable between a rest position when the displaceable platform is in a design position and an extended position when the displaceable platform is in a fully deployed position. 
     
     
         17 . The vehicle seat of  claim 16 , further comprising:
 a retention mechanism extending between the displaceable platform and the carrier assembly, wherein the retention mechanism is in a lowered position when the displaceable platform is in a design position, and wherein the retention mechanism is in a raised position when the displaceable platform is in a fully deployed position.   
     
     
         18 . The vehicle seat of  claim 17 , wherein the carrier assembly includes a carrier, wherein the retention mechanism includes first and second attachment members, and wherein the first and second attachment members are rotatably coupled to a tubular front segment of the carrier. 
     
     
         19 . The vehicle seat of  claim 18 , wherein the attachment member is coupled to a rear segment of the carrier, wherein the carrier assembly includes a panel disposed between the carrier and the displaceable platform, and wherein the T-shaped link connects the displaceable platform to the attachment member. 
     
     
         20 . A seating assembly comprising:
 a seatback;   a seat including:
 a cushion; 
 a displaceable platform; 
 a carrier assembly; and 
 a seat frame assembly; 
   wherein the carrier assembly is fixedly coupled to the seat frame assembly, wherein an attachment member and a pitch plate are disposed between the displaceable platform and the carrier assembly, and wherein the displaceable platform is rotatable relative to a front portion of the carrier assembly and slidable relative to a rear portion of the carrier assembly between a design position and a fully deployed position in response to a sudden vehicle deceleration.
