Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
218 words
An igniter comprising: an insulated cup made of an insulating member, the insulated cup for accommodating an igniting agent and a header, the insulated cup having a rear end, the rear end of the insulated cup adapted for engaging a harness supporter; an igniting agent in said insulated cup; a header for igniting the igniting agent, the header having a header case made of conductive metal, a glass sintered member charged into the header, a pair of lead electrodes inserted into the header at a certain interval therebetween, wherein each of the lead electrodes includes a leading end and a rear end, the rear end of each of the lead electrodes having a harness connected thereto, a heater member for heating the igniting agent, the heater member being bridged between the leading ends of the lead electrodes; and a harness supporter made of an insulating member, the harness supporter including a preformed mating section at a leading end of the harness supporter engaging the rear end of the insulated cup, the harness supporter having a pair of harnesses inserted into the harness supporter at a certain interval therebetween; whereby the insulated cup is joined to the harness supporter forming an igniter body; and one of the lead electrodes is electrically conducted to the header case grounding static electricity.
Claim 2
Dependent Claim
218 words
An igniter comprising: an insulated cup made of an insulating member, the insulated cup for accommodating an igniting agent and a header, the insulated cup having a rear end, the rear end of the insulated cup adapted for engaging a harness supporter; an igniting agent in said insulated cup; a header for igniting the igniting agent, the header having a header case made of conductive metal, a glass sintered member charged into the header, a pair of lead electrodes inserted into the header at a certain interval therebetween, wherein each of the lead electrodes includes a leading end and a rear end, the rear end of each of the lead electrodes having a harness connected thereto, a heater member for heating the igniting agent, the heater member being bridged between the leading ends of the lead electrodes; and a harness supporter made of an insulating member, the harness supporter including a preformed mating section at a leading end of the harness supporter engaging the rear end of the insulated cup, the harness supporter having a pair of harnesses inserted into the harness supporter at a certain interval therebetween; whereby the insulated cup is joined to the harness supporter forming an igniter body; and one of the lead electrodes is electrically conducted to the header case grounding static electricity.
