Abstract: Reinforcement is given in a vehicle seat with such an arrangement that a plurality of recessions and at least one decorative groove are scatteringly formed in each of two spaced-apart protuberant side support portions of the vehicle seat. A foaming is effected to create a foam padding of a predetermined shape of the seat having two spaced-apart protuberant side support portions, such as to define a plurality of first recessions and at least one first decorative groove in each of those two side support portions, after which, a trim cover assembly is pressingly bonded to the thus-formed foaming pad, thereby forcibly inserting and bonding plural points of the trim cover assembly in those first recessions and decorative groove of padding. A resulting seat is therefore provided not only with a highly enlarged area of cured and hardened adhesive layer, but also with an intensified stretched state of trim cover assembly, whereby an increased reinforcement is given to both two side support portions of the seat.

Abstract: In forming a donut-like headrest under a foaming process, a sealing garnish element is provided, which includes a garnish portion and an edge abutment portion. Prior to a foaming step, the sealing garnish element is brought to a donut-like trim cover assembly and inserted fit in an annular opening formed in the annular inward wall region of the trim cover assembly, such that the edge portions of the annular opening are abutted against the edge abutment portion of sealing garnish element, while the garnish portion is attached on and along the annular inward wall region of trim cover assembly. Hence, during the foaming step, those edge abutment and garnish portions of sealing garnish element effectively prevents a liquid foaming base material injected in the trim cover assembly, against leakage from the annular opening.

Abstract: Described herein is a drive-by-wire vehicle engine output control system. The system permits good-response acceleration by a driver's simple and reasonable operation, i.e., by operating an accelerator pedal and also a prompt response even when a sudden load change occurs. Further, the system permits precise speed control by simple equipment even when the deviation of a vehicle speed from a target vehicle speed is large. Output changes of an engine can be controlled within a permissible output change range by (a) comparing a target autocruise engine output with an acceleration demanding ending output, choosing the larger engine output and then controlling the engine to give the larger engine output, (b) controlling the engine to achieve a target autocruise engine output obtained from a speed correction torque and a running load torque or (c) limiting an engine control quantity on the basis of a permissible output change value.

Abstract: A die for pressingly bonding a foam padding to a covering member of assemblage of a vehicle seat, the foam padding being of a one-side-opened type having a hollow therein, which die includes an upper die comprising a main die portion and a movable die member connected hingedly thereto. The movability of such die member allows easy securement of the foam padding to the upper die, as the movable die member is easily inserted into the hollow of the padding, thereby allowing further insertion of the upper die on the whole into within the padding. When pressing the padding against the covering member by use of the upper die, the movable die member is moved within the padding to a position on the same horizontal line with the main die portion, giving a pressure evenly both padding and covering member for effective bonding of them.

Abstract: An antenna device is withdrawable from and receivable in a body of a portable radio device. A rodlike antenna is covered with a rodlike antenna cover, and a helix antenna to which an initial elastic strain is imparted is covered with a cap. A control portion of an electrically-conductive member is movably received in a groove formed in a portion of connection between the rodlike antenna cover and the cap. The rodlike antenna cover is supported on the body of the radio device. In an extended condition of the rodlike antenna, a connection portion of the electrically-conductive member is urged against the rodlike antenna by a restoring load of the helix antenna to electrically connect the spiral antenna to the rodlike antenna. In a retracted condition of the rodlike antenna, the electrically-conductive member is caused to abut against an antenna holder to be spaced apart from the rodlike antenna, thereby interrupting an electrical connection between the helix antenna and the rodlike antenna.
