Anti-Collision Office Chair

Anti-collision office chairs typically need to comply with the EN 1335 standard, which sets requirements in terms of design, safety, etc., to reduce the risk of injury to users. Details are as follows:

General Design Aspect:
The design of office chairs should focus on minimizing the risk of injury to users. Among them, the treatment of edges and corners is a crucial aspect. According to the standard, the edges and corners of office chairs must be rounded. This is because during daily use, users may inadvertently collide with the edges or corners of the chair. If the edges and corners are sharp, they can easily scratch or injure the user, while rounded treatment can effectively prevent such situations and ensure the user's physical safety.

Safety Aspect:

• Stability: Stability is an important indicator of the safety of office chairs. Office chairs need to remain stable under normal use and foreseeable misuse scenarios, without tipping over or tilting. To ensure this, the standard stipulates that office chairs must pass multiple stability tests, including seat front edge stability tests, forward stability tests, lateral stability tests, and rear stability tests. For chairs with footrests, due to their special structure and usage, additional forward stability tests are required to comprehensively evaluate their stability in different usage scenarios.
• Pinch Points and Sharp Edges: During the use of office chairs, adjustment and rotation are common operations. If the chair has pinch points or sharp edges during these processes, it may pinch the user's fingers or other body parts. Therefore, the standard requires that the chair should not cause pinching of fingers or body parts during adjustment and rotation, eliminating potential pinch points and sharp edges from the design to ensure the user's safety when operating the chair.
• Mechanical Adjustment Mechanisms: Pneumatic rods and explosion-proof devices are key components of office chairs, and the reliability of their performance is directly related to the user's safety. Pneumatic rods are used to adjust the height of the chair. If their performance is unreliable, they may suddenly drop or rise, causing injury to the user; explosion-proof devices can provide protection when the pneumatic rod malfunctions, preventing dangerous situations such as explosions. Therefore, the standard imposes strict requirements on the performance of these key components to ensure their reliable performance.
