A protective member such as a helmet includes an outer layer and an inner layer interconnected by multiple connectors, such as extension springs, under tension along their longitudinal axis. The connectors absorb energy from an impact force by resisting further tension along their longitudinal axis and allow the outer layer and inner layer to move relative to each other. In the helmet application, the head of a user experiences less impact force, reduced change in momentum or position of the head and neck, reduced head and neck loads and reduced amounts of linear and rotational acceleration. The protective member can be used in numerous applications and environments, including for participants in sports, in applications including bumpers, passenger cabins, car seats and beds.

A spring module for a spring cushion for furniture. includes a base (20), an end cap (30) and a spring (10) arranged between the base and the end cap. The end cap has a flexible connection portion (33) and is configured to be detachably fixed to the base (20). The flexible connection portion (33) is located radially inside the spring (10). The spring module provides improved stability. The spring cushion has a simple structure and is easy to assemble and disassemble. The disassembled spring modules can be compressed or stacked and nested to save storage and transportation space

An elastic pad for furniture includes a mounting layer, a plurality of elastic modules, an elastic balance net and a flexible cover. A plurality of raised blocks are arranged on a top surface of the mounting layer. Each elastic module is nested on one of the raised blocks, where an outer diameter of the raised block is greater than or equal to an inner diameter of the elastic module at a corresponding height. This allows the elastic modules to be mounted independently of one another. For example, if an elastic module is damaged, it can be removed for repair, without removing other elastic modules.
