Land Rover Discovery: Seatbelt System - Overview

A 3 point seatbelt is installed in all seating positions. Each seatbelt has emergency locking retractor functionality.

The emergency locking retractor function incorporates a lift shaft locking system with webbing sensor and car sensing activating mechanisms. The webbing sensor activates the locking mechanism if the webbing is subjected to a sharp pull. The car sensor activates the locking system if the vehicle is subjected to sudden deceleration or severe tilt angle.

A pretensioner is incorporated into the retractor of each front seatbelt and each third row seatbelt. The pretensioners, in the retractors are pyrotechnic devices that are controlled by the Restraints Control Module (RCM) in the Supplementary Restraint System (SRS).

For additional information, refer to: Airbag Supplemental Restraint System (501-20B Supplemental Restraint System, Description and Operation).

All row 2 passengers and front passenger emergency locking retractors are enhanced with automatic locking retractors North American Specification (NAS) only.

The automatic locking retractor allows webbing to be extracted to activate a ratchet device. This device allows webbing to be cinched tight to facilitate child seat fitment. With seatbelt webbing tensioned in automatic locking retractor mode the seatbelt is always locked.

A seatbelt warning indicator is installed in the Instrument Cluster (IC) to remind the all seat occupants to fasten their seatbelts. On NAS vehicles, when the ignition mode is accessory/convenience, the warning indicator illuminates if the seatbelt of an occupied front seat is not fastened. The warning indicator remains illuminated until the seatbelt of each occupied front seat is fastened, or the ignition mode is warning indicator is off. In all markets except NAS, a belt minder function provides a more intrusive reminder to fasten the front seatbelts.
