Filed:

Oct 2, 2001

Appl. No.:

09/969209

Inventors:

Michael Starozhitsky - Buffalo Grove IL
Matthew J. Reiter - Northbrook IL

Assignee:

Illinois Tool Works, Inc. - Glenview IL

International Classification:

C21D 104

US Classification:

148570, 148572, 148590, 280741, 29 123, 29 13, 298972, 72 3106, 723671

Abstract:

A selectively heat treated canister for use in a vehicle airbag deployment system is configured to contain combustion materials and to contain gases produced from the combustion thereof. The canister includes a tubular body having a length and a longitudinal axis. The body is formed as at least three drawn sections. Each prior section is drawn one more time than a successive adjacent section. The canister defines a closed end and an open end. The closed end is at a least drawn section and the open end is at a most drawn section. The canister defines a heat treated region and is selectively heat treated at least one transition zone between adjacent drawn sections to reduce crack propagation observed during testing. A method for making the canister is also disclosed.

International Classification:

F16B 13/06

US Classification:

411 601, 411 69, 411 72

Abstract:

A wedge-type anchor assembly, capable of meeting cracked concrete testing standards, comprises an anchor bolt component and a substantially C-shaped expansion sleeve component annularly disposed about the anchor bolt component. A plurality of annular grooves, threads, or teeth are disposed only about the forward end portion of the expansion sleeve component, as opposed to throughout the entire axial length thereof, so that when the anchor bolt component is moved axially through the expansion sleeve component, the maximum interference area (M. I. A. ) and maximum interference volume (M. I. V. ) can be generated between the anchor bolt component and the expansion sleeve component in a controlled and predictable manner, as well as between the expansion sleeve component and the internal peripheral side wall portions of a concrete substrate or substructure can be generated so as to enhance pull-out resistance and reliability of the anchor assembly within the concrete substructure or substrate. The expansion sleeve component may be plated with a tin-zinc (Sn—Zn) composition, and the rear end portion of the expansion sleeve component may have a larger diametrical extent than the forward end portion of the expansion sleeve component so as to enhance pull-out resistance.
