Stepping mechanism and adjusting device for a vehicle seat with the step mechanism

摘要

Stepping gears convert a continuous rotary motion into an intermittent rotary motion. Thus, the transmission output between the individual steps is stationary until the next step begins. Such step transmission find particular in vehicle seats for adjusting the seat application. For this purpose, a stepping mechanism 1 comprising an output unit 3 with an output element 6, wherein the output element 6 has internal teeth 24, a drive unit 4, with a first and second pawl 14a, b for transmitting a drive torque to the output element 6, wherein each of the two pawls 14a, b has an external toothing 23, the first pawl 14a has a first and the second pawl 14b a second control pin 16a, b, wherein the drive unit 4 has a pawl guide plate 8, wherein the pawls 14a, b in the pawl guide plate 8 between an engagement and a neutral position are performed, wherein the first and / or the second pawl 14a, b is controlled in the engaged position in the internal teeth 24 and in the neutral position of the internal teeth 24, proposed, wherein the drive unit 4 has a rocker arm 11 , wherein upon rotation of the pawl guide plate 8 about the Hauptdrehach H tilting lever 11 tilted relative to the pawl guide plate 8, so that at least one of the control pins 16a, b rests against the rocker arm 11 and the associated pawl 14a, b is controlled.
