Electronic module assembly for inflatable personal restraint systems and associated methods
First Claim
1. An electronics control module assembly (EMA) for an inflatable personal restraint system, the EMA comprising:
- a housing having a body portion, a cover portion that attaches to the body portion to form an enclosure, and a protrusion extending outwardly from the cover portion, wherein the protrusion has an outer boundary at which the protrusion projects away from the cover portion; and
a crash sensor positioned within the enclosure in an area defined by the outer boundary of the protrusion, wherein the protrusion forms an envelope of space around the crash sensor that defines a minimum distance that an external object with a magnetic field can come to the crash sensor without activating the crash sensor.

Abstract
Electronics module assemblies (“EMAs”) for inflatable personal restraints and associated systems are described herein. An EMA configured in accordance with an embodiment of the present technology can include, for example, a housing having a body portion, cover portion that attaches to the body portion to form an enclosure, and protrusion extending outwardly from the cover portion. The protrusion can have an outer boundary at which the protrusion projects away from the cover portion. The EMA can further include a crash sensor within the enclosure in an area defined by the outer boundary of the protrusion. The protrusion can form an envelope of space around the crash sensor that defines a minimum distance an external object with a magnetic field can come to the crash sensor without activating it. The EMA can optionally include a magnetic field configured to disable the crash sensor upon the detection of an external magnetic field.

10. An electronics control module assembly (EMA) for an inflatable personal restraint system, the EMA comprising:
-
a housing having a generally planar outer surface and protrusion extending outwardly from the generally planar outer surface; a deployment circuit configured to initiate inflation of an airbag; and a magnetically-activated crash sensor operably coupled to the deployment circuit and positioned within the housing, wherein the protrusion forms a clearance envelope around the crash sensor that defines a minimum distance that an external object with a magnetic field can come to the crash sensor without activating the crash sensor. - View Dependent Claims (11, 12, 13)

14. An inflatable personal restraint system, comprising:
-
a seatbelt having a deployable airbag; an inflator operably coupled to the airbag; and an electronics module assembly (EMA) operably coupled to the inflator and configured to initiate inflation of the airbag, the EMA having a housing and a crash sensor positioned in the housing, wherein the housing includes a generally planar surface and a protrusion extending from the generally planar surface, and wherein the crash sensor is positioned in an area defined by an outer boundary of the protrusion, the protrusion forming an envelope of physical space around the crash sensor that prevents activation of the crash sensor due to an external magnetic field. - View Dependent Claims (15, 16)
