この概要は現在英語のみで提供しています。

適用範囲

This standard applies to the seats, their anchorages, and head restraints of M1, N, and specific M2/M3 category vehicles. It also covers the design of seat back rear components and luggage displacement protection devices in M1 vehicles. It explicitly excludes rearward-facing seats and their associated head restraints. The standard is mandatory for all relevant automotive manufacturers and is technically aligned with ECE R17.

技術要求

The standard mandates strict general requirements, including the prohibition of side-facing seats in certain vehicle categories (M1, N1, and specific M2/M3 classes). It requires that all adjustment, displacement, and locking systems be self-locking. Seat back components must not feature any dangerous protrusions or sharp edges that could increase occupant injury, specifying minimum curvature radii for different impact zones. For head restraints, the standard specifies precise requirements for installation, height, width, and the gap between the head restraint and the seat back. Front row outer seats in M1 vehicles and specific M2/N1 vehicles must be equipped with head restraints. Head restraints must provide sufficient energy absorption and limit the maximum backward displacement of the head form to under 102mm during static testing to prevent cervical spine injuries. Additionally, it outlines special requirements for luggage displacement protection. Seat backs and partitioning systems acting as the front boundary of a luggage compartment must possess sufficient strength. During a frontal impact simulation, these structures must not allow luggage to penetrate the cabin space beyond strictly defined forward displacement limits relative to the seat's R-point.

試験方法

The standard employs a combination of static and dynamic testing procedures. Key evaluations include the seat back strength test, which applies a specific bending moment to simulate occupant loading. Dynamic tests involve applying a 20g longitudinal acceleration to the vehicle body to simulate front and rear impacts. Head restraints undergo a static performance test using a 165mm diameter head form to measure displacement and apply specific loads. Energy absorption is evaluated via a pendulum impact test (striking at 24.1km/h) to ensure deceleration limits are met. Luggage displacement protection is verified through a specialized dynamic sled test using standardized rigid test blocks to impact the seat back. ISO 6487 is referenced for measurement instrumentation.

よくある質問

What products and vehicle categories are regulated under GB 15083-2019?

It applies to M1, M2, M3, and N category vehicles, specifically covering seats, their anchorages, and head restraints. It explicitly excludes rearward-facing seats and their head restraints.

Are there any major updates from the previous GB 15083-2006 version?

The 2019 version prohibits side-facing seats in specific vehicle categories (M1, N1, certain M2/M3 classes), introduces definitions for various seat orientations (forward, rearward, side-facing, walk-in), and removes the static test method for anchorage and locking device strength, aligning more closely with ECE R17.

How does GB 15083-2019 differ from or relate to international standards like ECE R17?

The technical content of GB 15083-2019 is heavily referenced from ECE R17. Engineers familiar with ECE R17 will find the core compliance logic and test procedures highly similar, though Chinese-specific categorizations and mandatory implementation dates apply.

The summary above provides a high-level overview of GB 15083-2019.
