Abstract
Abstract In a motor vehicle, a seat arrangement having a seat portion and a backrest pivotably mounted on a common axle with the seat portion and tiltable between a first region of inclination corresponding to a sitting position and a second region of inclination corresponding to a rest position, a positioning device comprising an operating handle disposed at one side of the seat arrangement, first latching device coupled to the operating handle and affecting fine adjustments in the sitting position of the backrest, a second operating handle disposed on the other side of the seat arrangement, a second latching device coupled to the second operating handle and limiting the maximum region of fine adjustments within the sitting position by the first operating handle, the first operating handle affecting the fine adjustments independently of the second operating handle, but the first and second operating handles are actuated simultaneously for transferring the backrest into the rest position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
197 words
In a seat arrangement, for use in a motor vehicle, in combination, a seat portion and a backrest portion, said backrest portion being pivotably mounted relative to said seat portion about a first axis and tiltable between a first region of inclination corresponding to a sitting position and a second region of inclination corresponding to a rest position, positioning means comprising a first operatiNg device disposed at one side of said seat arrangement, first latching means releasably coupled to said first operating device and affecting fine adjustments in inclination of said backrest within said first region of inclination, a second operating device disposed on the other side of said seat arrangement, second latching means releasably coupled to said second operating device and limiting in the latching position thereof the maximum region of fine adjustments within said first region by said first operating device, said first and second latching means being rigidly connected together and tiltable in unison about a second axis spaced apart from said first axis, said first and second operating devices when actuated simultaneously releasing said first and second latching means for tilting said backrest about said first axis into said second region of inclination.
Claim 2
Dependent Claim
197 words
In a seat arrangement, for use in a motor vehicle, in combination, a seat portion and a backrest portion, said backrest portion being pivotably mounted relative to said seat portion about a first axis and tiltable between a first region of inclination corresponding to a sitting position and a second region of inclination corresponding to a rest position, positioning means comprising a first operatiNg device disposed at one side of said seat arrangement, first latching means releasably coupled to said first operating device and affecting fine adjustments in inclination of said backrest within said first region of inclination, a second operating device disposed on the other side of said seat arrangement, second latching means releasably coupled to said second operating device and limiting in the latching position thereof the maximum region of fine adjustments within said first region by said first operating device, said first and second latching means being rigidly connected together and tiltable in unison about a second axis spaced apart from said first axis, said first and second operating devices when actuated simultaneously releasing said first and second latching means for tilting said backrest about said first axis into said second region of inclination.
Claim 3
Dependent Claim
56 words
The combination as claimed in claim 1, wherein said latching means further includes adjusting members rigidly mounted on respective ends of a common axle, said backrest comprising a side frame having an elongated portion on each side of said seat arrangement, and means for coupling said elongated portions to the respective one of said adjusting members.
Claim 4
Dependent Claim
70 words
The combination as claimed in claim 2, wherein said first latching means comprises one of said adjusting members, recess means provided on said adjusting member corresponding to desired fine adjustment values of said backrest, locking means, spring means biasing said locking means into engagement with said recess means and securing said backrest in a predetermined position, one of said recess means corresponding to the maximum inclination in said first region.
Claim 5
Dependent Claim
29 words
The combination as claimed in claim 3, wherein said adjusting member has a segment-like portion, said recess means being formed like teeth about the periphery of said segment-like portion.
Claim 6
Dependent Claim
69 words
The combination as claimed in claim 2, wherein said second latching means comprises said second operating device formed as a handle pivotably mounted about a point of rotation, said handle having a portion formed as a latching surface, said other adjusting member engaging said latching surface when said first operating device is at its maximum position within said first region, thereby said second operating device limiting said maximum position.
Claim 7
Dependent Claim
56 words
The combination as claimed in claim 5, wherein said second operating device comprises a second limiting portion, said other adjusting member engaging said limiting portion in said second region and thereby preventing self-release of said backrest from said rest position, said second operating device being constructed to release said backrest from said locked position when operated.
