Abstract: A gas generator that can controllably allow the airbag to inflate and expand slowly at an initial stage of the inflation and thereafter inflate and expand rapidly so that the intended function of the airbag can be fulfilled. In the gas generator, an enclosed space (S) in a housing (1) is partitioned into two combustion chambers (3, 4), in which gas generating agents (6), a filtering member (7) and an igniter (8, 9) are arranged, respectively. The combustion chambers (3, 4) are communicated to each other through the filtering member (7). The igniters are operated with time difference so that the airbag can be inflated and expanded moderately by a small amount of gas generated in one combustion chamber at the initial stage of inflation and then is inflated and expanded rapidly by a large amount of gas generated in the respective combustion chambers, thus achieving multistage control of the expansion of the airbag.

Abstract: A gas generator for an air bag, including a combustion chamber and a hermetic container accommodated in the combustion chamber. Gas generant pellets are charged in the hermetic container. The hermetic container has a wall adapted to be destroyed during combustion of the gas generant pellets. A partition foil piece covers a surface formed by the gas generant pellets charged in the hermetic container so as to conform to a profile of the surface formed by the gas generant pellets. The partition foil piece is non-reactive with the gas generant pellets and has a strength lower than that of the hermetic container. A cushioning member presses the partition foil piece toward the gas generant pellets by a resilient force of the cushioning member so as to suppress movement of the gas generant pellets charged in the hermetic container.

Abstract: A wire harness grommet has a funnel-like shape having a wire-passing tubular portion of a small diameter, and a partition wall-mounting portion extending from the tubular portion. The bonding between a filler layer, which is provided in a hollow portion of the funnel-shaped portion, and an inner wall surface is enhanced to thereby prevent the separation of the filler layer. Removal of the grommet from a mold can be effected satisfactorily. The inner wall surface is in the form of tiling in which flat plateaus are densely arranged and spaced from one another by joint grooves, so that the inner wall surface serves as a separation prevention surface.

Abstract: A grommet comprising: a panel mounting portion which is mounted on an opening of a panel and has a large-diameter hole for loosely receiving a wiring harness; a wire receiving portion which is formed axially integrally with the panel mounting portion and has a small-diameter hole for closely receiving the wiring harness; the large-diameter hole being communicated with the small-diameter hole such that the wiring harness is inserted through the small-diameter hole and the large-diameter hole in an insertion direction oriented from the small-diameter hole to the large-diameter hole; and a plurality of ribs which are provided in the large-diameter hole so as to extend in parallel with the insertion direction of the wiring harness.

Abstract: An insulator for a terminal-connecting portion has a sufficient force for holding a terminal and can drain water efficiently. An insulator body 100 is provided with a draining hole 140 on a side wall part 133 which is one of the exterior walls forming a curved portion 130. Since the draining hole 140 is provided on the side wall part, an outer corner wall part 131 of the curved portion 130 is left intact and an inner peripheral face of the outer corner wall part 131 is closely and elastically mounted on a corner 64 of a female terminal 60. Since an inner peripheral face of another end 120 of the insulator body 100 is closely and elastically mounted on two corners 62 and 63 out of three remaining corners 61 to 64, the female terminal 60 is supported on three points, so that a sufficient force of holding a terminal can be obtained.

Abstract: An insulator (100) wherein a funnel portion (120) has a conical inner peripheral surface (121) of an inner diameter increasing in a direction away from a body (101). A male terminal (second terminal) (161) is inserted into the insulator (100) from the funnel portion (120) to mate with a female terminal (first terminal) (151) housed in the insulator (100), and a jig (170) is prevented from interfering with an edge of the funnel portion (120) of the insulator (100) as the male terminal (161) is securely pushed into the female terminal (151), thereby preventing connection failure between the first and second terminals. If the path of insertion of the male terminal (161) is shifted so that the male terminal (161) abuts against the inner peripheral surface (121), the path is corrected along the slope of the inner peripheral surface (121), facilitating the insertion of the male terminal (161).

Abstract: This invention is to provide a multipole connecting terminal which can join a plurality of electric cables in the same direction. The multipole connecting terminal comprises first and second terminal connecting portions 40a and 40b formed on the opposite sides of a first strip piece 21A of a metal plate 20 and third and fourth terminal connecting portions 40c and 40d formed on a second strip piece 21B bent toward the reverse side of the first strip piece 21A. The portions 40a, 40b, 40c, and 40d have openings in the same direction. It is possible to join each of male terminals 70 attached to each of electric cables 60 to each of the terminal connecting portions 40a through 40d while maintaining the cables 60 in a straight position without turning the cables 60. A connecting work of the male 70 becomes easy since the electric cables 60 are not turned around the multipole connecting terminal.
