An upper track member is slidingly coupled to the lower track member. The lower track member includes at least one slot formed therein. A lead screw having opposing first and second ends is disposed between the lower and upper track members. A support member is connected to the first and of the lead screw. The support member is additionally coupled to the lower track member. The support member includes at least one boss formed thereon. The at least one boss is received in the at least one slot of the lower track member for connecting a support member to the lower track member. The support member includes a neck portion deformable in response to bending of the lead screw for reducing breakage of the lead screw. ## Claims ### Claim 1 A seat adjusting assembly for a vehicle comprising: a lower track member secured to the floor of the vehicle; an upper track member slidingly coupled to the lower track member, the lower track member including at least one slot formed therein; a stationary lead screw having opposing first and second ends, the lead screw disposed between the lower and upper track members; a support member connected to the first end of the lead screw, the support member coupled to the lower track member, the support member including at least one boss formed thereon, the at least one boss received in the at least one slot of the lower track member for connecting the support member to the lower track member. ### Claim 2 (depends on 1) The seat adjusting assembly of claim 1 wherein the at least one boss comprises a rectangular projection and locks into the at least one slot formed in the lower track member. ### Claim 3 (depends on 1) The seat adjusting assembly of claim 1 wherein the support member includes a pair of bosses formed thereon, the pair of bosses received in a pair of slots formed in the lower track member. ### Claim 4 (depends on 1) The seat adjusting assembly of claim 1 wherein the lower track member includes a connecting hole formed therein for receiving a connecting element linking the support member and the lower track member. ### Claim 5 (depends on 4) The seat adjusting assembly of claim 4 wherein the connecting element is selected from the group consisting of screws, rivets, and bolts. ### Claim 6 (depends on 4) The seat adjusting assembly of claim 4 wherein the support member includes a connecting hole formed therein for receiving the connecting element. ### Claim 7 (depends on 1) The seat adjusting assembly of claim 1 wherein the support member includes a threading hole formed therein along an axis of the lead screw for connecting the lead screw and support member, the threading hole including proximal and distal ends. ### Claim 8 (depends on 7) The seat adjusting assembly of claim 7 wherein the threading hole includes a counter bore formed at the proximal end. ### Claim 9 (depends on 8) The seat adjusting assembly of claim 8 wherein the counter bore defines a thin neck portion of the support member, the thin neck portion deformable in response to bending of the lead screw for preventing breakage of the lead screw. ### Claim 10 (depends on 1) The seat adjusting assembly of claim 1 wherein the second end of the lead screw includes a stop washer disposed thereon. ### Claim 11 (depends on 1) The seat adjusting assembly of claim 1 including a drive assembly coupled to the lead screw and attached to the upper track member. ### Claim 12 A seat adjusting assembly for a vehicle comprising: a lower track member secured to the floor of the vehicle; an upper track member slidingly coupled to the lower track member, the lower track member including at least one slot formed therein; a stationary lead screw having opposing first and second ends, the lead screw disposed between the lower and upper track members; a support member connected to the first end of the lead screw, the support member coupled to the lower track member, the support member including a threading hole formed therein along an axis of the lead screw for connecting the lead screw and support member, the threading hole including proximal and distal ends. ### Claim 13 (depends on 12) The seat adjusting assembly of claim 12 wherein the threading hole includes a counter bore formed at the proximal end. ### Claim 14 (depends on 13) The seat adjusting assembly of claim 13 wherein the counter bore defines a thin neck portion of the support member, the thin neck portion deformable in response to bending of the lead screw for reducing breakage of the lead screw. ### Claim 15 A seat adjusting assembly for a vehicle comprising: a lower track member secured to the floor of the vehicle; an upper track member slidingly coupled to the lower track member, the lower track member including at least one slot formed therein; a stationary lead screw having opposing first and second ends, the lead screw disposed between the lower and upper track members; a support member connected to the first end of the lead screw, the support member coupled to the lower track member, The support member including a threading hole formed therein along an axis of the lead screw for connecting the lead screw and support member, the threading hole including proximal and distal ends, the proximal end having a counter bore defining a neck portion of the support member, the neck portion deformable in response to bending of the lead screw for reducing breakage of the lead screw.
