Abstract: Disclosed is a seat belt pretensioner device for moving a moveably supported seat belt buckle in a direction to increase the tension of a seat belt with a power generating device so as to automatically increase the tension of the seat belt in case of an impact situation. such as a vehicle crash. The power generator comprises a bladder-like member that can be pressurized for expansion, and a chamber defined for guiding the direction of the expansion of the bladder-like member. The buckle of the seat belt can be moved in the direction to increase the tension of the seat belt by pushing a member supporting the buckle with the bladder-like member.

Abstract: Provided is a vehicle seat assembly which can prevent a submarine phenomenon in a reliable manner, and which is simple in structure so as to allow a high level of flexibility in layout. A slip preventing member for preventing the vehicle occupant from slipping forward under the seat belt in case of an impact is supported by a fixed part of a seat so as to be pivotable between a retracted position and a raised position, and an actuator is interposed between a fixed part of said seat and a part of said slip preventing member. To retain the slip preventing member at its raised position even after the power of the power unit is all used up, the assembly further includes a lock mechanism for retaining said slip preventing member at said raised position.

Abstract: In a vehicle occupant restraint system provided in association with a vehicle seat for preventing a vehicle occupant from slipping forward under a seat belt in an impact situation such as a vehicle crash, a pair of support members are provided on either side of the seat frame, and pivotally support a pair of arms across which a cross member extends. The cross member comprises an energy absorbing structure adapted to undergo a controlled deformation under a load occurring as the front part of the seat bottom is raised. The energy absorbing structure may consist of a relatively deformable member wrapped around the cross member or a feature for controlling a mode of deformation of the cross member. When the cross member consists of a pipe member, the energy absorbing structure may comprise a relatively deformable member filled inside the pipe member or perforations formed in the pipe member.

Abstract: In a vehicle occupant restraint system provided in association with a vehicle seat for preventing a vehicle occupant from slipping forward under a seat belt in an impact situation such as a vehicle crash, a pair of casings are provided on either side of the seat frame, and pivotally support a pair of arms across which a cross member extends A power unit pivotally incorporated in at east one of the casings raises the arms and cross member in an impact situation. The casing is formed by a main member having a vertical section and a pair of Ranges extending from upper and lower ends of the vertical section, and a lid member attached to the free ends of the flanges. The hollow structure of the casing provides a high level of mechanical strength, and the two piece structure of the casing allows the assembly work to be performed in a simple manner because the components can be installed from sideways one after another in a relatively simple manner.

Abstract: Using a stereo viewing method, three-dimensional model data are produced that completely express an object in a three-dimensional shape, or moving images of the object as seen from any viewpoint are produced.

Abstract: Provided is a vehicle occupant restraint system which can reduce the load on the chest and head of the vehicle occupant in an impact situation while reliably preventing the submarine phenomenon. By restraining the pelvis and the adjacent parts of the vehicle occupant before the load is applied to the chest and head, the load is more favorably distributed, and the critical parts are favorably protected. This can be accomplished by activating a restraining member for raising an appropriate part of the vehicle seat immediate upon detecting an impact.

Abstract: In a pretensioner device for automatically increasing a tension of a seat belt in case of a vehicle crash which uses a piston and cylinder arrangement as a power generator, a spring member resiliently urges the piston assembly in the direction of actuation so that any play that may be present in each connecting potion of the path of power transmission can be eliminated. Therefore, collision between component parts at the time of activating the power generator can be prevented, and the loss of energy which could arise from such collision can be avoided. The piston assembly may comprise a piston main body slidably received in the cylinder, and a piston rod having a base end abutting an opposing end of the piston main body and a free end projecting out of the open free end of the cylinder while the cylinder is provided with an inwardly directed radial flange for preventing the piston main body from being projected out of the cylinder.

Abstract: A submarine preventing mechanism is arrange inside a seat. The submarine preventing mechanism is provided with brackets attached to a cushion flame, links, and a submarine preventing body supported by the links. The links have first ends rotatably supported by the brackets by means of support shafts, respectively. The links have second ends located at a lower level than the support shafts. The submarine preventing body includes a first rod, a second rod, and a gas generator for generating a gas with which the second rod is pulled into the first rod at the time of a vehicle collision. If the vehicle collision occurs, the gas generator burns, generating a gas. In response to this, the second rod is pulled into the first rod. Accordingly, the links are rotated upward, raising the submarine preventing body.

Abstract: In a pre-tensioner assembly for automatically increasing a tension of a seat belt in case of a vehicle crash, an arm is pivotally attached to a base plate at its one end and to a part of a seat belt, and a cylinder and piston device is attached to the base plate to selectively rotate the arm from a rest position to an operative position. Typically, the cylinder and piston device comprises a linear cylinder having a propellant placed in a bottom end thereof. The rotary arm for displacing a buckle or other part of the seat belt can be substantially directly connected to the piston of the actuator, and because the piston rod is pushed out of the cylinder when actuating the rotary arm, the pressure receiving surface of the piston can be maximized. Therefore, the power transmission efficiency is improved, and the required amount of the propellant can be reduced with the result that the size and the cost of the assembly can be minimized.

Abstract: A cause inferring device which infers causes with improved accuracy and efficiency. A phenomenon item (F) other than phenomenon items (A, B and C) for which frequency-of-occurrence data are already inputted is selected based on the degree of association data regarding cause items (2, 3 and 4) having the highest certainty among cause items (1-5) whose certainties are calculated. The frequency-of-occurrence data of the selected phenomenon item (F) and already inputted frequency-of-occurrence data are inputted again and the certainties of the cause items are computed. By repeating such selection and arithmetic processing at least once, causes are narrowed down as a final inference.

Abstract: A small-sized precision distance measuring apparatus. When a laser beam 1b reflected from an article is received on a photodetector array (30) through a lens array (20), the effective area of the photodetector array (30) is calculated on the basis of the output from the photodetectors, and the distance from the lens array (20) to the article 11 is calculated from the calculated area and the angle of view of the lenses constituting the lens array (20). If pixels (33a, 33b, 33c) of an image on a sensor array, corresponding to the coordinates of elements in the space (12), are determined on the basis of the positional relationship between the lenses (41a, 41b, 41c) of a lens array and photodetectors (51a, 51b, 51c) of the sensor array, the comparison of image information on the pixels (33a, 33b, 33c) can be made to determine the coordinate positions representing the profile of the article 11 from the coordinate positions of the space (12), thereby determining the distance to the article (11) and its shape.

Abstract: An apparatus for correctly inferring the causes of a failure of driving machine or the like. Each time a true cause is found, the data on the degree of relevance of the cause is so corrected that the degree of the other causes becomes high and those of the other causes become low. On the basis of the data on the failure rate and the data on the degree of the relevance, the certainty of each cause is inferred by a first inferring means. The data on the predicted failure rate of each cause and the data on the actual failure rate are compared, and the certainty of each cause is inferred by a second inferring means in such a way that the certainty of a cause having less errors becomes higher. The certainties inferred by the first and second inferring means are weighted in a predetermined way. Based upon these weighted certainties, final certainties are inferred.
