Description

TECHNICAL AREA

The present disclosure relates to adjusters for vehicle seats.

BACKGROUND

Vehicle seats can include slide position adjusters, easy entry systems, and / or ways to lay seats flat. Slide rail position adjusters can take into account the adjustment of the position of vehicle seats relative to the floor of the vehicle (e.g. in the longitudinal direction and / or vertically). Easy entry seat fixtures can be used to provide easier access to and / or exit from a rear part of the vehicle, such as access to a rear row of seats. For example, an easy entry seating system may include a backrest frame that is rotatable relative to a seat frame for movement between an angled range for comfort, an angled range for easy entry, and / or an angled range for storage space. An easy entry system may allow the seat frame to move forward beyond a range of comfort levels of seating positions. One way to lay down seats may include making the back frame so that it rotates forward to a generally horizontal position. Seat slide rails can be locked and / or unlocked depending on the position of the backrest frame. Conventional seats often use flexible cables and / or sheathed cables (e.g. Bowden cables) to connect various components of a seat, but such cables can be relatively expensive.

• - an easy entry position is operated.

DE 195 24 166 A1 describes a seat slide mechanism in which a forward-folding backrest rotates L-shaped angle connectors, which in turn operate locking levers to release slidable seat rails.

DE 10 2010 055 244 A1 describes a longitudinally adjustable vehicle seat in which the locking device of a pair of rails is actuated by means of a Bowden cable.

In DE 20 2013 100 547 U1 Another motor vehicle seat is described in which a locking means for moving the seat is unlocked by folding the backrest forwards into the easy-entry position.

The invention is based on the object of creating a linkage for a seat displacement mechanism which is adapted to the structural specifications of the vehicle seat and which offers a reliable function.

This object is achieved by a linkage for handling a seat according to claim 1. Advantageous further developments are given in the subclaims.
