Automotive modular seat frame assembly

A seat frame assembly for a vehicle and comprising;

• a pair of fixed rails extending fore and aft and being laterally spaced from one another,
• brackets attached to said fixed rails for attachment to the vehicle,
• a slide rail supported by each of said fixed rails for fore and aft movement relative to said fixed rails,
• at least one cross beam interconnecting said slide rails,
• a support sheet extending supported by said cross beam,
• a seat pan disposed above said support sheet for supporting an occupant, and
• a rear bladder and a front bladder disposed between said sheet and said pan for raising and lowering the respective back and front of said pan relative to said sheet.

• a slide rail supported by each of said fixed rails for fore and aft movement relative to said fixed rails,
• one of said fixed and slide rails being C-shaped channels with the other of said fixed and slide rails being slidably disposed in said C-shaped channel,
• a pair of front and rear cross beams interconnecting said slide rails for supporting all of the remaining components of a first seat supported totally on said cross beams,
• a pair of seat back flanges for supporting a seat back, said rear cross beam having an irregular cross section, each of said seat back flanges having an irregular opening complementary to and surrounding said cross beam for supporting a seat back on said rear cross beam,
• a support sheet extending between and supported by said cross beams,
• a seat pan disposed above said support sheet for supporting an occupant,
• a rear bladder and a front bladder disposed between said sheet and said pan for raising and lowering the respective back and front of said pan relative to said sheet,
• front linkages interconnecting said pan and said slide rails for guiding raising and lowering movement of the front of said pan, and
• rear linkages interconnecting said pan and said slide rails for guiding raising and lowering movement of the rear of said pan.

• a pair of fixed rails extending fore and aft and being laterally spaced from one another,
• said fixed rails comprising C-shaped channels defining openings which face one another,
• brackets attached to said fixed rails for attachment to the vehicle,
• a slide rail supported by each of said fixed rails for fore and aft movement relative to said fixed rails,
• said slide rails being slideably disposed in said C-shaped channels,
• a pair of front and rear cross beams interconnecting said slide rails for supporting all of the remaining components of a first seat supported totally on said cross beams;
• and
• said cross beams extending through said openings in said C-shaped channels with the ends thereof attached to said slide rails.

A seat frame assembly for a vehicle comprising;

• a first pair of fixed rails extending fore and aft and being laterally spaced from one another,
• brackets attached to said first fixed rails for attachment to the vehicle,
• a first slide rail supported by each of said first fixed rails for fore and aft movement relative to said first fixed rails,
• a pair of first front and rear cross beams interconnecting said first slide rails for supporting all of the remaining components of a first seat supported totally on said first cross beams,
• a second pair of fixed rails extending fore and aft and being laterally spaced from one:
• another,
• brackets attached to said second fixed rails for attachment to the vehicle,
• a second slide rail supported by each of said second fixed rails for fore and aft movement relative to said second fixed rails,
• a pair of second front and rear cross beams interconnecting said second slide rails for supporting all of the remaining components of a second seat supported totally on said second cross beams, and
• said brackets including frame members interconnecting adjacent slide rails of said first and second seats for defining a front seat assembly which may be installed into a vehicle as one unit.
