Abstract
Abstract The bottom portion of a folding front seat in a car is connected to the back seat portion by a hinge arrangement having three hinge plates mounted for relative angular movement on a single pivot pin. The first hinge plate is attached to the bottom portion, the second hinge plate may be adjusted angularly relative to the first plate and secured in each of a plurality of angularly adjusted positions, and the third plate may be swung on the hinge pin relative to the second plate between two terminal positions defined by abutments for folding the seat without disturbing the back rest adjustment set between the first and second plates.

Claim 1
Independent Claim
254 words
A hinge arrangement for a seat of a motor car comprising: a. first, second, and third hinge plate members; b. a pivot pin connecting said members for relative angular movement thereof about a first axis; c. first engaging means mounted on one of said second and third members for pivoting movement about a second axis; d. two second engaging means on the other one of said second and third members and alignable with said first engaging means respectively by pivoting of said second and third members relative to each other about said first axis between two terminal positions, 1. respective portions of said second and third members enveloping said first axis and being axially juxtaposed, 2. respective other portions of said second and third members projecting from said juxtaposed portions in a direction away from said axis, 3. the combined axial thickness of said juxtaposed portions being approximately equal to the axial thickness of onE of said other portions, 4. said one portion being axially coextensive with each of said juxtaposed portions; e. yieldably resilient means biasing said first engaging means toward engagement with the aligned second engaging means; and f. securing means for securing said second member to said first member in each of a plurality of angular positions, said securing means including 1. a toothed segment on said second member circularly arcuate about said first axis, 2. a toothed wheel rotatably mounted on said first member in meshing engagement with said segment, and 3. blocking means for blocking rotation of said wheel.
