A system includes a belt that is adjustable between a secured state where there is at least a threshold level of tension across the belt, and an unsecured state where there is less than the threshold level of tension across the belt. The system also includes a first antenna, a second antenna, and an alert. The first antenna is disposed at the belt, operable to transmit and receive wireless communications, and operable at a resonant frequency with the belt in the secured state and inoperable at the resonant frequency with the belt in the unsecured state. The second antenna is disposed remote from the belt and operable to transmit and receive wireless communications at the resonant frequency. The alert is generated based on receiving a wireless communication from the first antenna at the second antenna when the resonant frequency is achieved, indicating the belt is in the secured state.

A belt securement verification system includes a belt and a securement verification device connected to the belt. When a tension force on the belt exceeds a threshold corresponding to a desired belt tightness or a desired belt slackness, the securement verification device moves from a first configuration to a second configuration to indicate to a user that the belt has achieved the desired belt tightness or desired belt slackness.

In a system and a method for adjusting seat belt pressure, in which while a passenger in a vehicle is wearing a seat belt, a webbing shape and pressure applied to a passenger's body by webbing can be detected, and webbing pressure adjustment drive devices can be operated based on the detected data so that local pressure applied to the passenger's body by webbing can be reduced, thereby relieving seat belt pressure. The system can include body pressure sensors, a camera, a controller, and various webbing pressure adjustment drive devices.

A system for detecting improper use of a seatbelt on a seat in a work machine is disclosed. The system comprises: a plurality of detection devices disposed on a plurality of locations within a cab of the work machine; a detection strip/tape on a strategic location of the seatbelt and configured to be detected by the plurality of detection devices; a controller coupled in communication to the plurality of detection devices, the controller configured to: receive input signals from the plurality of detection devices, wherein at least one input signal is indicative of improper use of the seatbelt; and communicate control signals to at least one operational system associated with the work machine upon receipt of an at least one input signal indicative of improper use of the seatbelt.

Systems and methods for controlling operation of a vehicle are described herein. According to exemplary embodiments, an off-road vehicle includes a chassis, a seating area supported by the chassis, one or more sensors configured to acquire data to facilitate detecting whether one or more conditions are met for unrestricted operation of the off-road vehicle, and a control system. The control system is configured to acquire the data from the one or more sensors and restrict operation of the off-road vehicle responsive to determining that at least one of the one or more conditions is not met. The control system is configured to permit unrestricted operation of the off-road vehicle responsive to determining that the one or more conditions are met.

A system is described. The system comprises a sensor module and a control module. The control module comprises a processor and a memory. The memory stores a sensor control module including computer-readable instructions that when executed by the processor cause: communicate a first command to the sensor module to capture images of interior portions of the vehicle and occupants; determine first characteristics of occupant seats and second characteristics of the occupants; compare the first characteristics with the second characteristics; determine a tautness for the seat belt; communicate a second command to automatically actuate and route a seat belt with the tautness; and in accordance with at least one of facial expressions, postures and gestures of the occupants while automatically routing the seat belt, communicate a third command to enable manual adjustment of the seat belt based on a user input received through a user interface of an electronic unit.
