Patent ID: 7219955

Claim:
An anti-pinching folding chair, comprising: a front leg assembly; a rear leg assembly; a seat assembly pivotally connected to each of the front and rear leg assemblies; a connecting assembly pivotally connected to the front leg assembly and slidably connected to the rear leg assembly to enable the front and rear leg assemblies to pivot relative to each other between folded open and folded closed positions and to enable the connecting assembly to slide along and relative to the rear leg assembly between retracted and extended positions in correspondence with the front and rear assemblies pivoting between the folded open and folded closed positions; a locking assembly arranged to releasably lock the connecting assembly and the rear leg assembly to each other in at least one relative position, the locking assembly having a lock and a bias device chair arranged to bias the lock in a direction, each of the connecting and rear leg assemblies having respective bores that align with each other as the front and rear leg assemblies reach the folded open position, the locking assembly being arranged so that the bias device biases the lock into the respective bores as the respective bores align with each other, and a bushing disposed between the connecting assembly relative to the rear leg assembly to control an extent of sliding of the connecting assembly relative to the rear leg assembly by providing a snug fit between the bushing and the connecting assembly, the connecting assembly pivotally connecting to the front leg assembly by a clevis assembly, the connecting assembly including a shaft that slides within the rear leg assembly between retracted and extended positions, the shaft having two portions of different diameters with a seat transitioning between the two portions, the clevis assembly being fitted onto the portion of the shaft whose diameter is smaller that that of the other portion so as to limit travel of the clevis assembly relative to the shaft.
