Support Plate: Thickness 2.0mm ±0.1mm

Component Specifications

Definition

The Support Plate is a critical structural component within lumbar support mechanisms, designed to distribute mechanical loads, maintain ergonomic alignment, and provide a stable mounting surface for adjustment mechanisms. It ensures consistent force transmission from the actuator to the lumbar region while resisting deformation under cyclic loading.

Working Principle

Operates on principles of static equilibrium and load distribution, transferring forces from adjustment mechanisms (e.g., motors, levers) to the lumbar support surface while maintaining structural integrity through rigid or semi-rigid material properties.

Materials

Typically cold-rolled steel (CRS) grade 1008/1010, aluminum alloy 6061-T6, or glass-filled polyamide (PA6-GF30) for lightweight applications. Thickness ranges from 1.5mm to 3.0mm.

Frequently Asked Questions

What is the primary function of a Support Plate in lumbar support mechanisms?

It distributes mechanical loads and provides a stable base for adjustment components, ensuring ergonomic alignment and durability.

Can Support Plates be interchanged between different lumbar support models?

No, they are typically model-specific due to variations in mounting points, curvature, and load requirements.
