Occupant restraint systems for use in land vehicles and other vehicles are disclosed herein. A restraint system configured in accordance with an embodiment of the invention includes an elongate belt or web configured to extend across an occupant seated in a vehicle, such as a military land vehicle. A proximal end portion of the elongate web is operably coupled to a web retractor. The web retractor carries an electrically actuated web locking device operably coupled to an acceleration sensor. The acceleration sensor sends an electrical signal to the web locking device in response to vehicle acceleration in, for example, a vertical direction above a preset magnitude. The web locking device responds to the electrical signal by at least temporarily preventing the retractor from paying out web.
