Function

The pinion housing constitutes the bearings of a spur-gear drive positioned in a pumping mechanism for adjusting back rests.

Technical requirements

• Wear-resistant bearings
• Low transverse forces

Profitability

The bearings of the optimised variant are still made of use-hardened multiple spindle rotating parts, but now manufactured much more economically. The shaping sections under less tension are created by a plastic coating.

• Cost savings: 80%
