Seat Recliner Mechanism With Spring Coil Actuator - The pawl  is a generally inverted t-formed. The lowest part of the pawl  has tooth  that cooperatively have interaction tooth  at the recliner rod . In turn, the actuator mechanism is pivotally secured to the seat cushion.
What is needed is an improved linear seat recliner that may be effortlessly modified to house diverse loading requirements with the aid of using multiple nested springs that may be placed relative to every different in step with operational needs.
A ramification of spring units can be used to provide the important tensile forces. The spring unit may additionally contain two or greater compression springs nested one inside the different. The spring unit may also contain a spring having decreased diameter coils that sandwich the bigger diameter coils. The spring unit can also incorporate large diameter coils that sandwich smaller diameter coils.
One quit of the spring unit  abuts a flat portion  of the recliner rod  and the other end of the spring unit  abuts the actuator housing . The spring unit  inhibits axial motion of the seat returned toward the actuator housing , however yields to forces transmitted thereto by means of the occupant rotating the seat lower back.
Noise related to the spring unit  can be considerably reduced by varying the diameter of the springs at selected places at one or extra places alongside the period of the spring. The recliner rod  may also encompass surface irregularities , which include notches or enamel as visible in figs. 6 and seven. This feature is in particular full-size if a couple of nested springs are used, because the inner spring [32a] serves as a guide for the outer spring [32b].
