A control device for an occupant protection device includes a power supply unit and a controller. The power supply unit performs supply of power to a squib for activating the occupant protection device. The controller causes the power supply unit to perform the supply of power at a first timing when a first condition is satisfied and causes the power supply unit to perform the supply of power at a second timing when a second condition is satisfied. At least one of the controller and the power supply unit prohibits, for a predetermined time after performing the supply of power at an earlier one timing of the first and second timings, the supply of power at another timing when the first and second conditions are satisfied.

According to various implementations, a vehicle pyrotechnic initiator assembly includes an initiator that includes at least one electrode pin and a validation device in electrical communication with the at least one electrode pin. The validation device provides validation information about at least a portion of the initiator assembly and/or a safety device in which the initiator assembly is installed. The validation information may include a date associated with an expiration of the initiator assembly and/or the safety device. The validation information may also or alternatively include a manufacturer identity associated with a manufacturer of the initiator assembly and/or safety device. In some implementations, the validation device includes an electrical circuit and/or memory that stores the validation information. For example, the validation device may include an ASIC chip.

A side airbag device includes: a side airbag in a folded state; a gas generator that includes an attachment portion to be attached to a vehicle, and that is configured to generate inflation gas to be supplied to the side airbag; a wrapping sheet that covers peripheries of the side airbag and the gas generator, and that is breakable when the side airbag is deployed and inflated; and a wire harness that includes a connection end portion electrically connected to the gas generator, and that is led out to an outer portion of the wrapping sheet. The wire harness is provided with a first locking portion, and the wrapping sheet is provided with a second locking portion that is locked to the first locking portion.
