An airbag device includes an outer shell forming an airbag and having a vent hole, a restriction member for restricting gas flow through the vent hole, a first chamber having the vent hole, a second chamber, the inner panel partitioning the airbag into the first and second chambers and having a communication portion, and a tether member for connecting the restriction member and the inner panel. Gas is introduced into the first chamber and then into the second chamber. When the first chamber is filled with gas and the inner panel is tensioned, the tension exceeding a predetermined value is applied to the restriction member so that the vent hole is substantially closed. When the first chamber is not filled with gas and the inner panel loosens, the tension applied to the restriction member does not reach the predetermined value so that the vent hole is opened.

An airbag device includes an airbag and an inflator disposed at a side of a base portion of the airbag for inflating the airbag. The airbag is inflated such that distal ends thereof extend away from the base side of the airbag. The airbag includes a left half airbag to be inflated at a front left of a vehicle occupant, and a right half airbag to be inflated at a front right of the vehicle occupant. The distal ends of the left half airbag and the right half airbag are spaced part from each other to form an empty space therebetween facing the vehicle occupant when the airbag is inflated.

An elastomeric prosthetic implant having a shell and a patch providing a reinforced access region on the shell for introduction of manufacturing implements, such as a gel-filling tool. The shell may cover the entire inner face of the patch, or a substantial part thereof, and a peripheral edge of the patch and the shell cooperate to form a flush interface with no sudden surface steps on both interior and exterior surfaces of the implant. The removal of any surface steps eliminates undesirable tactile discontinuities and stress points that may cause the shell wall to wear or may irritate the surrounding tissues. The prosthetic implant may be a breast implant formed of a silicone elastomer. The patch may be the same material or a liquid silicone rubber, but at least has similar material properties such as elastic modulus, durometer and elongation. The patch may include a channel used for introducing silicone to the mold to form the shell, for venting the mold cavity during the mold process, and / or for introducing the silicone gel into the hollow prosthesis.

A vehicle tire 10 is provided. The tire 10 includes an outermost member 12 having a plurality of spaced aligned apertures 22 formed therethrough. An innermost member 28 is aligned in and adjacent to the outermost member 12. Additionally a plurality of spaced aligned elongated studs 40 are formed in the innermost member 28 in recesses 38 formed therein and aligned in a corresponding one of the apertures in the outermost member. The tire 10 further includes an air inflation member 36 for inflating the innermost member 28 so that the studs 40 formed thereon will move from a retracted recessed position to an extended position through the apertures in the outermost member 12 to provide additional surface traction for the tire.

An airbag that can inflate without using a high-power inflator, and an airbag apparatus provided with such an airbag are disclosed. In one form, the airbag, when inflating, has a normally open vent hole disposed in a rear panel in a region extending toward the center of a steering wheel from the rim of the steering wheel and an openable vent hole disposed in a region extending toward the outside of the steering wheel from the rim. The openable vent hole is covered by a cover. The cover and a strap inside the airbag are connected to each other with a tether. From the commencement of inflation of the airbag, the cover is placed over the openable vent hole to close the openable vent hole.

A machine for inflating and sealing an inflatable structure having a longitudinal edge generally comprises a drive, an inflation nozzle, a sealing device, and a sheet engagement device. The machine may define an engaging assembly and an opposing assembly. The drive may be rotationally coupled to the sheet engagement device such that when the drive rotates, the engagement device also rotates. The engagement device may include a first belt and an opposing second belt which may each have a plurality of teeth thereon. The teeth may intermesh between a drive roller and a backing roller on the longitudinal edge of the inflatable structure. Thereby, the sheets of the inflatable structure may be engaged together and the length of the longitudinal edge may contract to facilitate inflation. The resulting inflated inflatable structure may comprise an embossed longitudinal edge.

An airbag for protecting an occupant includes a panel forming the airbag and having an occupant counter surface with a head counter portion to face a head of the occupant when the airbag is inflated. A recess portion is formed in the head counter portion when the airbag is inflated. The airbag also includes a regulation member for regulating inflation of the head counter portion toward the occupant. The regulation member forms the recess portion by regulating inflation of the head counter portion toward the occupant upon inflation of the airbag. The regulation member is configured to release regulation after a predetermined time from a moment when the airbag starts inflation.
