Abstract
Abstract A seat recliner having a linear recliner mechanism and a memory dump mechanism. The linear recliner mechanism includes a housing fixed to the seat bottom and a recliner rod supported for selective movement relative to the housing. The memory dump mechanism includes a second housing secured to the seatback and which is supported on the recliner rod for movement between a memory position and a free position relative to the recliner rod. A latch assembly is provided for releasably latching the second housing to the recliner rod in the memory position. When the second housing is secured in the memory position, the linear recliner mechanism can be selectively actuated to adjust the reclined position of the seatback between upright and fully-reclined positions. When the latch assembly is actuated, the second housing can be slid toward the free position in response to movement of the seatback toward its dumped position. Optionally, the latch assembly can also function to latch the second housing to the recliner rod in the free position for latching the seatback in its dumped position. Subsequent return of the seatback from its dumped position causes the second housing to again be secured in the memory position so as to locate and retain the seatback in its previously reclined position.

Claim 9
Dependent Claim
37 words
The seat recliner of claim 7 wherein said second rod end being in said first position when said seatback is in said angular position and said second position when said seatback is in said forward dumped position.
Claim 10
Dependent Claim
159 words
The seat recliner of claim 8 wherein said latch assembly of said memory dump mechanism in said release mode is adapted to permit sliding movement of said second housing relative to said recliner rod from said first position toward said second position, wherein said latch assembly of said memory dump mechanism in said unreleased mode is operable for releasably latching said second housing to said second rod end in said first position whereat the seat occupant can selectively adjust the angular position of the seatback by selectively shifting said recliner mechanism into an angle adjusting mode, and wherein movement of the seatback from said forward dumped position to said angular position causes said second housing to slide from said second position to said first position whereat said latch assembly of said memory dump mechanism is automatically shifted into its unreleased mode for retaining said second housing in said first position and thereby retaining the seatback in said angular position.
