Abstract
A passenger restraint system includes a seatbelt buckle mechanism which includes a tongue having an aperture for receiving the belt and a pair of opposing recesses formed in an opposite edge of the tongue. A housing is provided for receiving a tongue and a latch is pivotably attached to the housing for locking the tongue to the housing. A retainer is provided for releasably locking the housing and latch and a solenoid is disposed in an operative relationship with the retainer for moving the retainer out of engagement with the latch in a remote manner. Apertures in the housing and latch enable mechanical access to the retainer for moving the retainer out of engagement with the latch independent of this solenoid if desired or necessary.
Description
- The present invention generally relates to systems for safely restraining passengers and is more particularly directed to systems for the restraint of passengers on an amusement ride.
- Seatbelt locking devices have been developed for allowing operators to control the locking and unlocking of seatbelts. Typically, the seat belt locking system includes a buckle portion into which a latching tongue is inserted and held by a retractable element.
- The latching tongue can be removed from the buckle by depressing a releasing lever.
- While each of the seat belt buckles should be operable remotely, there is also a need for individual operation of the belts, if necessary, upon loss of electrical power.
- Accordingly, there is a need for a seatbelt locking system which can be activated by a remote operator, other than the user of the seat belt and for determining the status of each seatbelt before operation of the amusement ride. Further, there is a need for a seatbelt locking system, or passenger restraint system, which enables override of the operators' locking of each of the seatbelt buckles.
- A passenger restraint system in accordance with the present invention generally includes a seatbelt buckle mechanism which, in turn, includes a tongue having an aperture for receiving a belt and a pair of opposing recesses are formed in opposing edges of the tongue.
- A housing is provided with a base and upstanding sidewalls for receiving the tongue therebetween along with the latch pivotably attached between the upstanding sidewalls and spaced apart from the housing body for enabling the tongue to pass thereunder.
- The latch includes depending sidewalls and spaced apart depending lugs which are receivable by the tongue opposing recesses for locking the tongue to the housing upon closing of the latch onto the housing. A spring mechanism is provided for holding the latch in a closed position and a retainer is also provided for latching engaging the housing and latch sidewalls for preventing pivoting of the latch. Thus, once latched, the tongue cannot be removed from the housing.
- Removal of the tongue is enabled by a solenoid which is disposed in an operative relationship with the retainer for moving the retainer out of engagement with the latch sidewall. The solenoid is remotely operated and enable, independent or simultaneous operation of a plurality of a seatbelt buckles.
- Apertures in the housing sidewall and the latching sidewall which are aligned with one another enable mechanical access to the retainer for moving the retainer out of engagement with the latch sidewall independent of the solenoid. This, in effect, provides an override for enabling individual opening of seatbelt buckles.
- For remote operation, a controller is provided for operating the solenoids.
- A plurality of seatbelt buckle mechanisms may be part of a passenger restraining system which may also include a plurality of seats disposed on a conveyor.
- Each of the belt buckles include a tongue sensor for indicating full insertion of the tongue into a housing between the upstanding sidewalls and a latch sensor for indicating closure of the latch. Thus, each belt buckle mechanism of the system may be remotely monitored by a operator/controller.
- The present invention may be more readily understood by consideration of the following detailed description when taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 is a perspective view of passenger restraint system in accordance with the present invention generally illustrating a seatbelt buckle mechanism, a tongue, housing, and latch along with extending belt portions; -
