An igniter arrangement for vehicle occupant protection devices includes a substrate, an electronic assembly on the substrate in an electronic zone, an electrical ignition bridge on the substrate in a pyrotechnic zone, and a pyrotechnic charge adjoining the ignition bridge. A shock absorbing elastic
An igniter arrangement for vehicle occupant protection devices includes a substrate, an electronic assembly on the substrate in an electronic zone, an electrical ignition bridge on the substrate in a pyrotechnic zone, and a pyrotechnic charge adjoining the ignition bridge. A shock absorbing elastic first material covers a first portion of the substrate in the pyrotechnic zone, and forms a shock-absorbing cushion between the charge and the electronic zone. A second material harder than the first encases a second portion of the substrate and the electronic assembly in the electronic zone, protects the electronic assembly, and separates the two zones. The ignition bridge and the electronic assembly are at opposite ends of the elongate substrate. A breakable parting feature separably connects the two substrate portions and breaks due to high forces arising during ignition of the charge, so these forces are not transmitted through the substrate into the electronic zone.

The printer as claimed in claim 1, wherein said image carrier comprises an intermediate image transfer body. 3. The printer as claimed in claim 1, wherein said chain comprises a pair of chains spaced from each other in an axial direction of said image carrier and each being passed over a respective pair of toothed pulleys, said pair of chains extend substantially perpendicularly to an axis of said image carrier and run substantially in parallel to each other, and said clamper is affixed at opposite ends thereof to said pair of chains substantially in parallel to the axis of said image carrier. 4. The printer as claimed in claim 3, wherein a space between said pair of chains is greater than a maximum sheet size available with said printer in a direction perpendicular to the direction of sheet conveyance. 5. The printer as claimed in claim 3, wherein pairs of toothed pulleys over which said pair of chains are respectively passed are fixed in place with teeth thereof aligning with each other in the axial direction of said image carrier. 6. The printer as claimed in claim 1, wherein a driving one of said pair of pulleys is positioned at a downstream side of said image transfer region, and a tense run of said chain is closer to said image carrier than the other run. 7. The printer as claimed in claim 1, wherein a driven one of said pair of toothed pulleys is configured to adjust tension acting on said chain. 8. The printer as claimed in claim 1, further comprising a stabilizing mechanism positioned in said image transfer region for maintaining a position of said chain relative to said image carrier. 9. The printer as claimed in claim 1, wherein said image carrier accommodates therein an image carrying member part of which is selectively wrapped around said image carrier, an image being formed in part of said image carrying member wrapped around said image carrier. 10. The printer as claimed in claim 9, wherein said image carrying member comprises a thermosensitive, water-repellent printing plate. 11. A printer comprising: at least one image carrier; and a sheet conveying device for conveying a sheet to which an image is to be transferred from said image carrier; said sheet conveying device comprising: a chain driven to run through an image transfer region, which is positioned immediately adjacent said image carrier, from an upstream side to a downstream side in a direction of sheet conveyance; a clamper affixed to said chain for clamping the sheet fed at a sheet feed position, which is located at an upstream side of said image transfer region; and a stabilizing mechanism positioned in said image transfer region for maintaining a position of said chain relative to said image carrier, wherein said stabilizing mechanism comprises: an idler pulley for maintaining the position of said chain relative to said image carrier; and a pressing roller facing said idler pulley for nipping said chain between said pressing roller and said idler pulley. 12. The printer as claimed in claim 11, wherein said pressing roller is resiliently held in contact with said chain and retractable, when said clamper passes said pressing roller, on contacting said clamper. 13. A printer comprising: at least one image carrier; and a sheet conveying device for conveying a sheet to which an image is to be transferred from said image carrier; said sheet conveying device comprising: a chain driven to run through an image transfer region, which is positioned immediately adjacent said image carrier, from an upstream side to a downstream side in a direction of sheet conveyance; and a clamper affixed to said chain for clamping the sheet fed at a sheet feed position, which is located at an upstream side of said image transfer region; wherein said clamper is affixed to said chain such that said clamper, clamping the sheet, conveys said sheet in a direction substantially tangential to said image carrier, and wherein said clamper is con
