Abstract
Abstract A fixed-angle adjusting mechanism for use in an automobile seat assembly, for example, comprises a fixed member having a latch member, a movable member angularly movably mounted on the fixed member and having a pawl member engageable with the latch member in a desired angular position, a control lever angularly movably mounted on the fixed member and actuatable for disengaging the pawl member from the latch member, a memory member engageable with the latch member in response to actuation of the control lever, a limiting member angularly movably mounted on the fixed member, and engageable with the pawl member for preventing the latter from engaging the latch member in response to actuation of the control lever and responsive to coaction with the memory member for disengaging from the pawl member, and means acting on the memory member for positioning the latter in an angular position corresponding to the desired angular position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
148 words
A fixed-angle adjusting mechanism comprising: (a) a fixed member having a latch member; (b) a movable member angularly movably mounted on said fixed member and having a pawl member engageable with said latch member in a desired angular position; (c) a control lever angularly movably mounted on said fixed member and actuatable for disengaging said pawl member from said latch member; (d) a memory member engageable with said latch member in response to actuation of said control lever; (e) a limiting member angularly movably mounted on said fixed member, and engageable with said pawl member for preventing the latter from engaging said latch member in response to actuation of said control lever and responsive to coaction with said memory member for disengaging from said pawl member; and (f) means acting on said memory member for positioning the latter in an angular position corresponding to said desired angular position.
Claim 2
Dependent Claim
148 words
A fixed-angle adjusting mechanism comprising: (a) a fixed member having a latch member; (b) a movable member angularly movably mounted on said fixed member and having a pawl member engageable with said latch member in a desired angular position; (c) a control lever angularly movably mounted on said fixed member and actuatable for disengaging said pawl member from said latch member; (d) a memory member engageable with said latch member in response to actuation of said control lever; (e) a limiting member angularly movably mounted on said fixed member, and engageable with said pawl member for preventing the latter from engaging said latch member in response to actuation of said control lever and responsive to coaction with said memory member for disengaging from said pawl member; and (f) means acting on said memory member for positioning the latter in an angular position corresponding to said desired angular position.
Claim 3
Dependent Claim
32 words
A fixed-angle adjusting mechanism according to claim 1, wherein said memory member has a second pawl member actuatable into engagement with said latch member in response to actuation of said control lever.
Claim 4
Dependent Claim
37 words
A fixed-angle adjusting mechanism according to claim 2, wherein said memory member is pivotably mounted on one of said first-mentioned pawl member, said fixed member, and said movable member, and angularly movable relatively to said movable member.
Claim 5
Dependent Claim
25 words
A fixed-angle adjusting mechanism according to claim 3, wherein said means comprises a resilient member interposed between said memory member and said first-mentioned pawl member.
Claim 6
Dependent Claim
63 words
A fixed-angle adjusting mechanism according to claim 2, including first cam means disposed between said control lever and said first-mentioned pawl member for bringing the latter into and out of engagement with said latch member, and second cam means disposed between said first-mentioned pawl member and said memory member for bringing said memory member into and out of engagement with said latch member.
Claim 7
Dependent Claim
58 words
A fixed-angle adjusting mechanism according to claim 5, wherein said first cam means comprises an engagement pin mounted on said movable member and a guide hole defined in said control lever and receiving therein said engagement pin, said latch member having first teeth engageable with said first-mentioned pawl member and second teeth engageable with said second pawl member.
