摘要： An occupant restraint air bag assembly includes an air bag having a base wall portion communicating with an inflator and a face wall for contacting the occupant upon inflation of the bag. A vent opening is provided in the base wall portion of the air bag for venting a portion of the inflation gas from the air bag to the occupant compartment. A valve flap carried by the air bag is operable to a position closing the vent opening to contain the inflation gas within the air bag. A tether has a first end connected to the valve flap and a second end attached to the face wall so that the inflation of the air bag and consequent displacement of the face wall pulls the tether to close the valve flap. The vent opening is preferably a plurality of spaced apart openings and the tether progressively moves the valve flap across the openings to progressively close the vent opening in response to the progressive travel of the face wall toward the occupant. If desired, one or more additional vent openings with flap valves may be provided and operated by tethers of different operative lengths to provide selected and variable control over the venting of inflation gas from the air bag in response to displacement of the bag.
摘要翻译：乘员约束气囊组件包括具有与充气器连通的底壁部分的气囊和用于在袋充气时使乘客接触的面壁。在气囊的底壁部分设有排气口，用于将一部分膨胀气体从气囊排出到乘员舱。由气囊承载的阀瓣可操作到关闭通气口的位置，以将充气气体容纳在气囊内。系绳具有连接到阀瓣的第一端和附接到面壁的第二端，使得气囊的膨胀以及随后的面壁的位移拉动系绳以关闭瓣膜。排气口优选地是多个间隔开的开口，并且系绳响应于面壁向乘员的逐渐行进而逐渐地将阀瓣横过开口移动以逐渐关闭通气口。如果需要，可以通过不同的操作长度的系绳来提供具有瓣阀的一个或多个另外的通气孔，以响应于袋的移位而对来自气囊的充气气体的排气进行选择和可变的控制。

摘要： An air bag valve assembly for installation in an opening in the fabric wall of an air bag includes first and second housing panels of flexible sheet material which overlie one another and are permeable to pass gas therethrough. The edge portions of the housing panels are stitched together to form a housing envelope in which a valve flap panel of flexible sheet material is supported. A tether is attached to the valve flap panel to move the valve flap panel across the gas permeable first and second panels when the tether is actuated. The valve assembly may be normally closed by using a gas impermeable material for the valve flap panel. Alternatively, the valve assembly may be normally open and then the actuation of the tether pulls a gas impermeable valve flap across the gas permeable first and second panels to block the flow of gas. The housing panels may be of a gas impermeable fabric having holes cut therein, or the panels may be an open weave mesh construction to pass gas therethrough.

摘要： A knee joint for the leg of an anthropomorphic dummy of the type used in vehicle crash testing comprises a femur member including a disk portion with a widened rim and a central axial opening, a tibia member, at least one first joint member pivotably attached to the femur member adjacent the central axial opening and including a slide track thereon with a stop surface at the forward end thereof, friction surfaces on the first joint member and disk portion just outside the central axial opening, adjustment apparatus extending through the central axial opening effective to adjust the axial force and thus the friction force between the friction surfaces, at least one second joint member fixed to the tibia member slidably attached to the slide track of the first joint member for sliding movement toward and away from the stop surface in a direction substantially perpendicular to the tibia member and at least one resilient member disposed between the first and second joint member and having a pair of opposing surfaces fixed to the first and second joint members, respectively, whereby sliding movement of the second joint member away from the stop surface generates a restoring force opposing said movement.
