Manually operated car seat
A hand lever adjusts the seat stroke by stroke. ASOM plays back the strokes automatically and shows the manual force for different seat occupancies in one diagram.

Motor-driven car seat
An electric motor adjusts a car seat. ASOM shows the torque and power of the motor for different seat occupancies – and what difference a torsion spring makes.

The task
One motor, different seat occupancies
An electric motor drives the four-bar linkage via a gear pair and moves the seat through all extreme positions. The torque and power it needs depend on how the seat is occupied. The system also contains a torsion spring whose characteristic curve influences the required motor torque.
What ASOM shows here
- The drive control automatically moves the seat through all extreme positions.
- Torque and power at the location of the motor, in parallel for different seat-occupancy load cases.
- Change the characteristic curve of the torsion spring, and you see the effect on the motor torque in real time.
Your benefits
Tune drive and spring together
You see immediately how the spring and the seat occupancy change the motor torque, and you design the drive to match from the start.
The right motor size
You know the torque and power for every occupancy before the motor is selected. More on force calculation
Fewer prototypes
You check on the model, not on the prototype, whether the motor and spring match.
All occupancies at a glance
One diagram per quantity with all load cases, instead of many individual calculations. More on diagrams
