Manually operated car seat

A hand lever adjusts the car seat stroke by stroke. ASOMv10 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.
  • ASOMv10 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.
