摘要： The partial differential equations inputted with respect to an unknown quantity A are processed according to the finite element method in which simultaneous first-order equations equivalent to the partial differential equations are obtained, and then a matrix equation equivalent to the simultaneous first-order equations, namely, (k.sub.ij) (a.sub.i)=(d.sub.i) is processed to derive a coefficient {a.sub.j } so as to generate a program which calculates the unknown quantity A. For each group of a plurality of elements, the program calculates a contribution determined by the positions of the nodes associated with the elements with respect to a portion of matrix element group such as k.sub.lm and k.sub.ll and a portion of constant group such as d.sub.l and d.sub.m determined by the numbers assigned to a plurality of nodes contained in the group of a plurality of elements and then generates the final values of the matrix element group {k.sub.ij } and the constant {d.sub.i } from the contribution calculated for each group of a plurality of elements.

摘要： A vehicle occupant protection apparatus for use in a vehicle includes an occupant-protecting expansion part caused to expand in the form of a curtain in the vehicle cabin along windows. The expansion part is attached to the vehicle body at two attachment points positioned forward and rearward of the windows. A tension line that joins the two attachment points is in a position where the expansion part is extended between the two points, and is positioned below the lower edges of the windows.

摘要： A sun visor for a vehicle includes a shaft 10 angularly movably mounted on a roof surface within a passenger compartment of the vehicle, and a shielding plate angularly movably mounted on the shaft 10. A holder 30 and a stabilizer 70, in which the shaft 10 is angularly movably inserted, are provided at an end portion of the shielding plate, and a first projection 20A and a second projection 20B are formed on the shaft 10, and are spaced from each other in a direction of an axis of the shaft. The distance between the second projection 20B and the tubular portion 71 is larger than the distance between the first projection 20A and the bearing portion 33.
