A damper structure provided in a steering wheel of a vehicle to be able to achieve an improved effect of reducing vibration in a low frequency region and structurally prevent noise generation. The damper structure includes a plate member which faces the steering wheel and to which an airbag module is to be attached, an insulator attached to the plate member, a connector inserted into the insulator and having one end fixed to the steering wheel to be oscillated by vibration of the steering wheel, an elastic member surrounding the connector in the insulator, a ring provided with the elastic member to transmit the oscillation of the connector to the elastic member, a stopper provided around another end of the connector to face the elastic member, and a coil spring which brings the elastic member of the insulator into pressure contact with the stopper.

Damper structure provided in steering wheel of vehicle

This steering wheel structure has: a steering wheel main unit; a horn block; a support block; horn contacts; and a horn spring, wherein the support block has: a lock member; and an elastic body, wherein a load bypass member is provided that transmits an operation load in a push-in direction, which has been applied to the horn block, to the lock member while circumventing the elastic body, and wherein the load bypass member is configured so as to be in a non-contact state between itself and at least either of the horn block side and the lock member side when the horn block is in a vicinity of a default position, and so as to be brought into contact with the horn block side and the lock member side in a manner capable of transmitting a load when the horn block is pushed in by a predetermined amount or greater.

Steering wheel structure

A steering wheel of a vehicle includes a steering wheel main body. The steering wheel main body includes a rim part, a boss part, a core metal, and a resin layer. The core metal includes a ring part and an offset part such that a distance from a center of the boss part to the offset part is smaller than a distance from the center of the boss part to the ring part. The resin layer includes a ring part resin layer covering the ring part, and an offset part resin layer covering the offset part. A thickness of the offset part resin layer at an outer side of a radial direction with respect to the offset part is thicker than a thickness of the ring part resin layer at the outer side of the radial direction with respect to the ring part. The resin layer is a complete circle.

Steering wheel of vehicle and manufacturing method of steering wheel of vehicle

An air bag is formed by sewing a first basic fabric opposed to an occupant and a second basic fabric on the opposite side, at a sewn portion along an outer peripheries of the fabrics. The air bag is folded in a longitudinally longer shape, and an oblong restricting member is wound around a central portion of the air bag to fix the air bag in a bundling manner, and then the air bag is vertically folded. In the process of expansion of the air bag, the air bag bundled by the restricting member is first expanded vertically and then expanded laterally after breakage of a breaking portion of the restricting member which cannot withstand a tension. Thus, by providing the restricting member, the shape and direction of the air bag can be controlled as desired in the process of deployment.
