Claim 2

In a vehicle seating assembly the combination comprising: a support frame supporting at least one seat; a seat back assembly mountable to said support frame; and mounting means for mounting said seat back assembly on said support frame for reclinable movement relative to a normal generally upright position, said mounting means including a fixed pivot means secured to said support frame and an adjustable pivot means carried by said support frame, said back assembly having first and second pivot receptors, said fixed pivot means having a first pivot pin which is received by said first pivot receptor, said adjustable pivot means having a second pivot pin aligned coaxially with said first pivot pin and said adjustable pivot means being constructed and arranged for movement horizontally along said support frame toward and away from said fixed pivot means between a first position in which said second pivot pin is received by said second pivot receptor and a second position in which said second pivot pin is disengaged from said second pivot receptor, and locking means for releasably securing said adjustable pivot means to said support frame to maintain said adjustable pivot means at said first position, thereby maintaining said first and second pivot pins of said fixed and adjustable pivot means in receiving engagement with said first and second pivot receptors to mount said seat back on said support frame for pivotal movement relative thereto, and said locking means being releasable to permit said adjustable pivot means to be moved to said second position permitting removal of said seat back from said support frame.

Claim 3

A vehicle seating assembly according to claim 1 wherein said first pivot pin is fixedly mounted on said support frame, and wherein said adjustable pivot means comprises a bracket adapted for sliding movement along said support frame and carrying said second pivot pin therewith.

Claim 4

A vehicle seating assembly according to claim 1 wherein said frame supports a pair of seats and a pair of seat back assemblies are mountable to said support frame, and including one of said mounting means for each back assembly.

Claim 5

A vehicle seating assembly according to claim 3 further comprising an armrest assembly for each of said back assemblies, each armrest assembly being cantilever mounted on said support frame.

Claim 6

A vehicle seating assembly according to claim 4 wherein the armrest assemblies are identical in construction and the back assemblies are identical in construction.

Claim 7

A vehicle seating assembly according to claim 1 which further comprises support means including a pedestal mount for supporting the frame above the floor of a vehicle and for attaching the seating assembly to the floor of the vehicle.

Claim 8

A vehicle seating assembly according to claim 6 wherein said support means includes means for removably attaching the pedestal mount to the underside of said support frame near the center thereof.

Claim 9

In a vehicle seating assembly the combination comprising: a support frame supporting at least one seat; a seat back assembly mountable to said support frame, and mounting means for mounting said seat back assembly on said support frame for reclinable movement relative to a normal generally upright position, said mounting means including a fixed pivot means seacured to said support frame and an adjustable pivot means carried by said support frame, said back assembly having first and second pivot receptors, said fixed pivot means having a first pivot pin which is received by said first pivot receptor, said adjustable pivot means having a second pivot pin aligned coaxially with said first pivot pin, and said adjustable pivot means being constructed and arranged for movement horizontally along said support frame toward and away from said fixed pivot pin means between a first position in which said second pivot pin is received by said second pivot receptor and a second position in which said second pivot pin is disengaged from said second pivot receptor, and locking means for releasably securing said adjustable pivot means to said support frame to maintain said adjustable pivot means at said first position, thereby maintaining said first and second pivot pins of said fixed and adjustable pivot means in receiving engagement with said first and second pivot receptors to mount said seat back on said support frame for pivotal movement relative thereto, and said locking means being releasable to permit said adjustable pivot means to be moved to said second position permitting removal of said seat back from said support frame, and said seat back having a back seat cushion portion which includes a layer of a soft foam material having first and second surfaces; a layer of upholstery material coerving said foam material at its first surface and defining the outer surface of the back seat cushion portion, said foam material having at least one groove formed therein on its first surface; and shaping means drawing into said groove the upholstery material which extends adjacent to said groove to create a pillowed configuration for the upholstered outer surface of said back seat cushion.

Claim 10

In a vehicle seating assembly the combination comprising: a support frame supporting at least one seat; a seat back assembly mountable to said support frame, and mounting means for mounting said seat back assembly on said support frame for reclinable movement relative to a normal generally upright position, said mounting means including a fixed pivot means seacured to said support frame and an adjustable pivot means carried by said support frame, said back assembly having first and second pivot receptors, said fixed pivot means having a first pivot pin which is received by said first pivot receptor, said adjustable pivot means having a second pivot pin aligned coaxially with said first pivot pin, and said adjustable pivot means being constructed and arranged for movement horizontally along said support frame toward and away from said fixed pivot pin means between a first position in which said second pivot pin is received by said second pivot receptor and a second position in which said second pivot pin is disengaged from said second pivot receptor, and locking means for releasably securing said adjustable pivot means to said support frame to maintain said adjustable pivot means at said first position, thereby maintaining said first and second pivot pins of said fixed and adjustable pivot means in receiving engagement with said first and second pivot receptors to mount said seat back on said support frame for pivotal movement relative thereto, and said locking means being releasable to permit said adjustable pivot means to be moved to said second position permitting removal of said seat back from said support frame, and said seat back having a back seat cushion portion which includes a layer of a soft foam material having first and second surfaces; a layer of upholstery material coerving said foam material at its first surface and defining the outer surface of the back seat cushion portion, said foam material having at least one groove formed therein on its first surface; and shaping means drawing into said groove the upholstery material which extends adjacent to said groove to create a pillowed configuration for the upholstered outer surface of said back seat cushion.
