Motor-driven car seat
An electric motor moves the seat to all extreme positions. ASOM shows torque and power for different seat occupancies – and immediately what difference a torsion spring makes.
Example · Automotive · ASOM
Manually operated car seat
A hand lever adjusts the car seat stroke by stroke. ASOM plays back the lever strokes automatically and shows the manual force for different seat occupancies in one diagram.

The task
Stroke by stroke to the end position
The mechanism consists of a four-bar linkage that a hand lever drives via a gear pair. Because the lever has only a limited angular range, it takes several strokes for the rear rocker to reach its end angle – each with a load stroke and a return stroke. How much manual force is required also depends on the seat occupancy.
What ASOM shows here
- The drive control executes the lever strokes automatically until the seat reaches its end position.
- ASOM shows the manual force at the lever for both the load stroke and the return stroke.
- Different seat-occupancy load cases calculated in parallel, all results in one diagram.
Your benefits
The manual force for all seat occupancies in view
Instead of recalculating individual strokes, you see the entire adjustment process at once.
Motion sequences without program code
You assemble loops and conditions from blocks; even long adjustment processes run by themselves. More on motion sequences
Comfort for every occupancy
You see immediately whether the manual force remains comfortable for light and heavy occupants alike. More on force calculation
Every change in all curves
Change the lever or the gear ratio, and all four curves change immediately.

Kinetostatic sensor field
Where should the hand apply force? ASOM shows the manual force for many application points at once in one diagram – even while you move the points.
