Office Chair for Investigation Area

The office chair for the investigation area is a special functional equipment designed specifically for law enforcement investigation venues such as public security bureaus, procuratorates, courts, and discipline inspection and supervision commissions. It needs to meet requirements for safety, controllability, ease of operation, and compliance.

Core Functions and Design Features

1. Safety Restraint and Anti-Escape Design
   • The office chair for the investigation area (such as the chair for suspects in interrogation rooms) ensures interrogation safety through multiple physical restraint mechanisms. For example, the base is fixed with embedded anchor bolts to prevent the chair from being moved; the adjustable and lockable backrest restricts the sitting posture of the person being questioned; the dual-limiting mechanism of ankle and wrist restraints uses stainless steel to achieve three-point restraint (ankle restraint + wrist restraint + back lock) to prevent self-harm or escape.
   • Key structures such as anti-pry bolts, a hard PVC surface layer + high-density flame-retardant substrate ensure that the equipment is impact-resistant and difficult to damage.
2. Materials and Environmental Standards
   • It needs to pass the B1-level flame-retardant + E0-level environmental double certification. Flame-retardant treatment prevents smoldering caused by untreated thick sponges when exposed to open flames; environmental requirements prevent the release of excessive formaldehyde from poorly glued soft packages under high temperatures, ensuring indoor air quality.
   • Common material combinations are a hard PVC surface layer (wear-resistant and easy to clean) + high-density flame-retardant substrate (fire-resistant and deformation-resistant) + stainless steel limiting parts (corrosion-resistant and damage-resistant).
3. Visual Management and Psychological Intervention
   • Color selection needs to comply with the "Regulations on the Setup of Law Enforcement Investigation Venues of Public Security Organs." For example, green can reduce the anxiety of the person being questioned and also facilitate the rapid identification of personnel positions in surveillance footage, improving management efficiency.

Installation Adaptability Requirements

• The floors in investigation areas are mostly anti-static PVC or epoxy floors. Some tables and chairs need to be fixed with embedded steel plates or chemical anchors. If expansion screws are used directly on non-standard concrete floors, the equipment stability may be affected due to insufficient floor strength, leading to looseness.
• Common dimensions: The chair for suspects in interrogation rooms is 580×520×850mm, and the matching interrogation table is 1400×700×720mm. Planning needs to be done in advance according to the spatial layout.

Practical Application Cases

• The Beiguan Police Station of the Lanling County Public Security Bureau once purchased one office chair for the investigation area from the Lanling County Zhou Wenzhong Furniture Business Department at a transaction amount of 4,680 yuan. This case reflects the importance that grassroots units attach to equipment compliance and supplier qualifications, and the procurement process needs to comply with government procurement regulations.

Types and Applicable Scenarios

• Chair for suspects in interrogation rooms: Suitable for formal interrogation rooms and detention transition areas, emphasizing non-adjustable inclination and a fully restrained structure to ensure absolute safety during the interrogation process.
• Other types: Some investigation areas may be equipped with ordinary office chairs (without restraint functions) for auxiliary positions such as police record-keeping and surveillance, but they need to comply with flame-retardant and environmental standards.
