Process 100 then proceeds to a sixth step 106 in which seat-bottom platform 30 is coupled to seat-bottom frame 28 by first and second platform mounts 45, 46 and platform support 48 as shown in FIGS. 3 and 14. After platform retainer 50 is mated with platform-retainer receiver 52, seat-bottom platform 30 is coupled to seat-bottom frame 28 in a fixed position so that movement of seat-bottom platform 30 in any direction other than back along installation axes 53, 54 is blocked.
Process 100 then proceeds to a seventh step 107 in which seat back 14 is positioned to cause seat-back slide rails 21, 22 to be aligned along alignment axes 25, 26 as suggested in FIG. 3 and shown in FIG. 15. As a result, seat-back slide rails 21, 22 mates with seat- back rail receivers 23, 24 as seat back 14 is lowered into position as suggested in FIGS. 16-17.
Process 100 proceeds to an eighth step 108 in which seat back 14 is coupled to seat bottom 12 as a result of seat-back slide rails 21, 22 mating with seat- back rail receivers 23, 24 as shown in FIGS. 3 and 17. After seat-back slide rails 21, 22 mate with seat- back rail receivers 23, 24, movement of seat back 14 relative to seat bottom 12 in any direction other than back along alignment axes 25, 26 is blocked.
Process 100 proceeds to a ninth step 109 in which seat- back cushions 71, 72 are arranged to be placed on seat back 14 and seat- bottom cushions 35, 36 are arranged to be placed on the seat bottom as suggested in FIGS. 3 and 18. Process 100 then proceeds to a tenth step 110 in which seat- bottom cushions 35, 36 are arranged to rest on and be supported by seat-bottom platform 30 as suggested in FIGS. 3 and 19. Also during tenth step 110, seat- back cushions 71, 72 are arranged to be supported in part by seat back 14.
Process 100 is shown in a series of sequential steps 101-110. However, the process of assembling seat 10 may be performed in any suitable combination of parallel and serial steps. The steps included in a process for assembling seat 10 may be performed in any suitable order. Disassembly of seat 10 occurs in the reverse of process 100 and also does not require tools.
