Abstract
Abstract The driver''s seat in a motor car is equipped with pivotally mounted detents normally held out of engagement with racks on the seat base by gravity or by weak springs, but engaged upon sudden acceleration or deceleration to prevent shifting of the seat if the latch associated with the conventional seat adjusting mechanism fails, or if it happens to be disengaged by the driver at the moment of sudden speed change.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
324 words
A seat arrangement for a motor vehicle comprising: a. a base member and main locking system; b. a seat member mounted on said base member for adjusting movement in a predetermined direction; c. an inertia operated auxilary locking system comprising a row of alternating teeth and gaps extending in said direction on one of said members, said teeth being fixedly secured to said one member; d. a two-armed lever mounted on the other member for pivoting movement about an axis transverse to said direction, 1. one arm of said lever having a terminal pawl portion shaped for being lockingly received in said gaps in a first angular position of said lever, 2. the other arm of said lever having a terminal contact portion shaped to prevent said contact portion from being received lockingly in said gaps; and e. biasing means biasing said lever toward a second angular position, 1. said contact portion sequentially engaging said teeth during said movement of said seat member while said lever is in said second position, 2. said pawl portion clearing said teeth in said second position of said lever, and 3. said pawl portion being spaced from said contact portion in said direction, the auxilary locking system further comprising a pivot pin on said other member, said lever being mounted on said pivot pin for pivoting movement about said axis, guide means on said other member for guiding said pivot pin transversely to said direction and said axis between an operative position remote from said row and a locking position adjacent said row, said pawl portion clearing said teeth in said second angular position of the lever and said contact position clearing said teeth in said first angular position of said lever when the lever is in said operative position, said pawl portion being received in one of said gaps and said contact portion abuttingly engaging one of said teeth in said locking position of said pivot pin.
Claim 2
Dependent Claim
324 words
A seat arrangement for a motor vehicle comprising: a. a base member and main locking system; b. a seat member mounted on said base member for adjusting movement in a predetermined direction; c. an inertia operated auxilary locking system comprising a row of alternating teeth and gaps extending in said direction on one of said members, said teeth being fixedly secured to said one member; d. a two-armed lever mounted on the other member for pivoting movement about an axis transverse to said direction, 1. one arm of said lever having a terminal pawl portion shaped for being lockingly received in said gaps in a first angular position of said lever, 2. the other arm of said lever having a terminal contact portion shaped to prevent said contact portion from being received lockingly in said gaps; and e. biasing means biasing said lever toward a second angular position, 1. said contact portion sequentially engaging said teeth during said movement of said seat member while said lever is in said second position, 2. said pawl portion clearing said teeth in said second position of said lever, and 3. said pawl portion being spaced from said contact portion in said direction, the auxilary locking system further comprising a pivot pin on said other member, said lever being mounted on said pivot pin for pivoting movement about said axis, guide means on said other member for guiding said pivot pin transversely to said direction and said axis between an operative position remote from said row and a locking position adjacent said row, said pawl portion clearing said teeth in said second angular position of the lever and said contact position clearing said teeth in said first angular position of said lever when the lever is in said operative position, said pawl portion being received in one of said gaps and said contact portion abuttingly engaging one of said teeth in said locking position of said pivot pin.
Claim 3
Dependent Claim
36 words
the other arm of said lever having a terminal contact portion shaped to prevent said contact portion from being received lockingly in said gaps; and e. biasing means biasing said lever toward a second angular position,
Claim 4
Dependent Claim
36 words
the other arm of said lever having a terminal contact portion shaped to prevent said contact portion from being received lockingly in said gaps; and e. biasing means biasing said lever toward a second angular position,
Claim 5
Dependent Claim

Claim 9
Dependent Claim
137 words
said pawl portion being spaced from said contact portion in said direction, the auxilary locking system further comprising a pivot pin on said other member, said lever being mounted on said pivot pin for pivoting movement about said axis, guide means on said other member for guiding said pivot pin transversely to said direction and said axis between an operative position remote from said row and a locking position adjacent said row, said pawl portion clearing said teeth in said second angular position of the lever and said contact position clearing said teeth in said first angular position of said lever when the lever is in said operative position, said pawl portion being received in one of said gaps and said contact portion abuttingly engaging one of said teeth in said locking position of said pivot pin.
Claim 10
Dependent Claim
137 words
said pawl portion being spaced from said contact portion in said direction, the auxilary locking system further comprising a pivot pin on said other member, said lever being mounted on said pivot pin for pivoting movement about said axis, guide means on said other member for guiding said pivot pin transversely to said direction and said axis between an operative position remote from said row and a locking position adjacent said row, said pawl portion clearing said teeth in said second angular position of the lever and said contact position clearing said teeth in said first angular position of said lever when the lever is in said operative position, said pawl portion being received in one of said gaps and said contact portion abuttingly engaging one of said teeth in said locking position of said pivot pin.
Claim 11
Dependent Claim
31 words
