Abstract:

A vehicle seat includes a seat back frame with an upper subframe pivot. A seat back subframe is pivotably connected to the seat back frame at the upper subframe pivot. An actuation assembly pivotably moves the seat back subframe relative to the seat back frame about the upper subframe pivot, between a seat back subframe design position and a subframe recline position. In the recline position a lower edge of the seat back subframe is positioned outwardly relative to the seat back frame with the seat back subframe pivoted to an angle relative to the seat back frame.

Abstract:

A damper is arranged between the seat backrest and the seat base. This damper applies a resistance to seat backrest movement, especially movement from the vertical position to the folded position. The damper includes a pin and profile mounted on the seat backrest and seat base respectively, or vice versa. The pin and profile slide against each other during movement of the seat backrest relative to the seat base. The shape, size, material, and/or the surface characteristics of the pin and profile determine the resistance to movement of the seat backrest. These parameters of the pin and profile can be varied, especially along different portions of the profile to apply the desired resistance at different angular positions of the seat backrest with respect to the seat base.
