AIRCRAFT OCCUPANT RESTRAINT PRETENSIONING DEVICES, SYSTEMS AND METHODS
First Claim
1. An occupant restraint system for use in an aircraft, the occupant restraint system comprising:
- a flexible and elongate web configured to extend across at least a portion of an occupant seated in a seat;
an electronically-actuated pretensioner operably coupled to an end portion of the web; and
a sensor assembly operably connected to the pretensioner, wherein the sensor assembly is configured to send an electrical signal to the pretensioner in response to an aircraft acceleration or deceleration above a preset magnitude, and wherein, in response to receiving the electrical signal from the sensor assembly, the pretensioner is configured to automatically increase tension in the web.

Abstract
Occupant restraint systems for use with aircraft occupant restraint systems and other restraint systems, and associated devices and methods are disclosed herein. In one embodiment, an occupant restraint system can include a flexible web configured to extend across at least a portion of a lap of an occupant positioned on a seat of an aircraft, and an electronically-actuated pretensioner operably coupled to an end portion of the web. The system can also include a sensor assembly operably coupled to the pretensioner, wherein the sensor assembly is configured to send an electrical signal to the pretensioner in response to an aircraft acceleration or deceleration above a preset magnitude, and wherein, in response to receiving the electrical signal from the sensor assembly, the pretensioner is configured to automatically increase tension on the web.

17. A seating system for use in an aircraft, the seating system comprising:
-
an aircraft seat, wherein the seat is mounted to a floor that defines a horizontal axis of the seat; a flexible and elongate web configured to extend across a lap of an occupant seated on the seat, wherein the web includes— a first web portion having a first distal end portion and a first proximal end portion; a second web portion have a second distal end portion and a second proximal end portion; and wherein the first distal end portion is releasably coupleable to the second distal portion via a buckle; and an electronically-actuated pretensioner fixedly mounted proximate the seat, the pretensioner including— a housing; and a cable, wherein the cable has a first cable portion extending within the housing and a second cable portion extending between the housing and the first web portion, wherein the second cable portion is coupled to the first proximal end portion of the first web portion, wherein the second cable portion extends along a tensioning axis, and wherein the tensioning axis extends at an angle that is less than 45 degrees relative to the horizontal axis of the seat when the web extends across the lap of the seat occupant. - View Dependent Claims (18, 19, 20, 21, 22, 23)
