Abstract: A vehicle seat headrest assembly (20) includes a headrest (21) having a rear headrest portion (28) with a housing (29) mounted on vertical posts (26) for vertical movement and also includes a front headrest portion (30) having a housing (31) movable longitudinally in forward and rearward directions by a support linkage (46) under the control of a rack and pinion mechanism (62). A first helical spring locking clamp (44) permits upward adjusting movement of the headrest but normally prevents downward movement, and a second helical spring locking clamp (72) permits forward movement of the front headrest portion housing (29) while normally preventing rearward movement. An actuator (36) releases the first and second helical spring locking clamps (44 and 72) to permit downward movement of the headrest (21) and rearward adjustment of the front headrest portion (30) housing (31).

Abstract: A vehicle armrest assembly (20) includes an armrest (22), a ratchet mechanism (24) having a linear ratchet plate (36) that cooperates with a pawl locking assembly (38) to permit vertical adjustment of the armrest. An upper armrest portion (100) is mounted on an armrest housing (96) by a track (102) for adjustable movement. An adjuster (114) of the armrest permits pivotal adjustment of the armrest as well as pivoting to a nonuse position.

Abstract: A vehicle seat support frame assembly (14) has a seat cushion base member (16) with opposite ends (20) and (22) pivotally connected to first and second legs (28, 40). The first legs (28) are also pivotally connected to the associated vehicle and the second legs (40) have first and second latches (50) and (52). Each first latch (50) provides securement of the associated second leg to the associated vehicle in the seating position, and each second latch (52) prevents pivoting between the second leg and the seat cushion base member end (22) to provide rigidity in the seating position.
