JP 2001-130419 A

  In the vehicle steering device described in Patent Document 1 described above, when the tilt memory or the telescopic memory is fixed at a desired position (memory position) within the setting range, a position defined by the tilt memory or the telescopic memory. It is possible to adjust the steering wheel holding position in the range up to (memory position) (limited area within the setting range), but adjust the steering wheel holding position beyond the above position (memory position). In this case, it is necessary to release the tilt memory or the telescopic memory, move the tilt memory or the telescopic memory together with the steering wheel, and fix the tilt memory or the telescopic memory at a new position (new memory position).

  For this reason, for example, in the range up to the position (memory position) set by the main user of the vehicle using the tilt memory or the telescopic memory, the set position described above by the secondary user (the user who temporarily uses the vehicle) When adjusting the holding position of the steering wheel without changing the (memory position), even if the main user subsequently adjusts the holding position of the steering wheel using the tilt memory or the telescopic memory, the above-described set position ( The steering wheel returns to the memory position and no problems occur.

  However, when a secondary user adjusts the steering wheel holding position beyond the set position (memory position) described above, the tilt memory or the telescopic memory is released, and the tilt memory or the telescopic memory is stored in the steering wheel. And fixed at a new position (new memory position). Therefore, when the main user thereafter adjusts the holding position of the steering wheel using the tilt memory or the telescopic memory, the steering wheel returns to a new position (a new memory position adjusted by the subsequent user). In this case, it is inconvenient because the main user needs to adjust the holding position of the steering wheel and the fixed position of the tilt memory or the telescopic memory again.

  The present invention is made to cope with the above-described problem. For example, when the main user of the vehicle sets the holding position of the steering wheel to a desired position within the setting range using the memory, the setting is performed. There is provided a vehicle steering apparatus in which a subordinate user can arbitrarily adjust the holding position of the steering wheel over the entire set range without exceeding the set position (memory position) without releasing The purpose is that.

  In order to achieve this object, in the present invention, the holding position of the steering wheel provided between the vehicle body side bracket and the column side bracket cannot be adjusted by the locking operation of the holding position adjusting operation lever, and is set by the unlocking operation. In a vehicle steering apparatus including a holding position adjusting mechanism (for example, at least one of a tilt adjusting mechanism and a telescopic adjusting mechanism) that can be adjusted within a range, a memory is stored in the column side bracket with respect to the holding position adjusting mechanism. The steering wheel is provided so as to be movable in the holding position adjustment direction, and a memory position adjusting operation lever capable of fixing and releasing the memory with respect to the column side bracket is provided. When adjusted to a desired position within the setting range, When the memory is fixed to the column side bracket by providing an engaging portion that is elastically and detachably engaged with the holding portion that does not move when the holding position of the wheel is adjusted, the engaging portion of the memory Is set so that a sense of moderation can be obtained when engaging and disengaging from the holding portion, and when the memory is released from the column side bracket, the engaging portion of the memory It is characterized in that the memory is set so as to move relative to the column side bracket and adjust the position with respect to the column side bracket while being engaged with the holding portion.

  In this vehicle steering apparatus, for example, the main user of the vehicle unlocks the holding position adjusting operation lever so that the holding position of the steering wheel can be adjusted within the set range by the holding position adjusting mechanism. At the same time, in a state where the memory position adjusting operation lever is released to release the fixation of the memory to the column side bracket, the steering wheel is moved over the entire range within the set range to engage the engaging portion of the memory with the holding portion. After moving, hold the memory lever in the desired position, fix the memory position adjustment lever, and lock the holding position adjustment lever. The memory is fixed to the column side bracket in the engaged state, and the steering wheel holding position cannot be adjusted. Is, the steering wheel is held in a desired position.

  For this reason, in the steering device in the above-described state, for example, when a user following the vehicle unlocks the holding position adjusting operation lever, the memory is fixed to the column side bracket. The holding position of the steering wheel can be adjusted within the set range by the holding position adjusting mechanism. At the time of the adjustment, when the desired position is passed, that is, the engaging portion of the memory with respect to the holding portion. A moderation feeling is obtained when engaging and disengaging. In addition, after the subordinate user adjusts the holding position of the steering wheel to an arbitrary position, the steering wheel can be held at an arbitrary position by locking the operation lever for holding position adjustment.

  In this state, since the memory is not released from being fixed to the column side bracket, the main user subsequently unlocks the holding position adjusting operation lever to adjust the holding position of the steering wheel. The main user can recognize the desired position of the steering wheel desired by the user by a sense of moderation when the engaging portion of the memory engages and disengages from the holding portion. Therefore, the main user can hold the steering wheel at a desired position by locking the holding position adjusting operation lever at a position where this sense of moderation is obtained.

  Further, when the present invention is implemented, when the memory position adjusting operation lever is disposed close to the holding position adjusting operation lever and the holding position adjusting operation lever is operated from the unlock position to the locked position by the locking operation. In addition, the memory position adjusting operation lever can be set to be operated from the release position to the fixed position.

  In this case, as described above, the holding position adjusting operation lever is unlocked, the memory position adjusting operation lever is released, and the steering wheel is moved over the entire region within the set range, and then the desired operation is performed. If the memory position adjustment operation lever is forgotten to be fixed in a series of operations, such as holding the position and fixing the memory position adjustment operation lever, and locking the holding position adjustment operation lever, the holding position adjustment As the operation lever is locked, the memory position adjusting operation lever can be operated from the release position to the fixed position, that is, the memory position adjusting operation lever can be fixed. For this reason, it is possible to prevent forgetting to fix the memory position adjusting operation lever.

And the memory position adjusting operation lever 151 is released to release the fixation of the memories 152 and 155 with respect to the column side bracket 132. The steering wheel is moved over the entire region within the setting range in the tilt direction so that the portion 152b1 is engaged with the holding recess of the vehicle body side bracket, and the engagement recess 155b1 of the second engagement element 155 is moved to a part of the bolt 133 ( The steering wheel in the telescopic direction to engage with the holding part) 133e. When the entire area within the fixed range is moved and held at a desired position, the memory position adjusting operation lever 151 is fixed, and the holding position adjusting operation lever is locked. The portion 152b1 is elastically and detachably engaged with the holding recess of the vehicle body side bracket, and the engaging recess 155b1 of the second memory 155 is elastically and detachable with a part (holding portion) 133e of the bolt 133. In a state where both the memories 152 and 155 are fixed with respect to the column side bracket 132, the holding position of the steering wheel is disabled and the steering wheel is held at a desired position.

  For this reason, in the steering apparatus of the third embodiment in the above-described state, for example, when the user who follows the vehicle unlocks the holding position adjusting operation lever, both the memories 152 and 155 become the column side bracket 132. The steering wheel holding position can be adjusted within the setting range by the tilt adjustment mechanism and the telescopic mechanism in a state where the steering wheel is fixed, and when the adjustment is made, the steering wheel passes through the desired position. That is, when the engaging convex portion 152b1 of the memory 152 is engaged with or disengaged from the holding concave portion of the vehicle body side bracket, the engaging concave portion 155b1 of the second memory 155 is part of the bolt 133 (holding portion) 133e. A moderation feeling can be obtained when engaging and disengaging. In addition, after the subordinate user adjusts the holding position of the steering wheel to an arbitrary position, the steering wheel can be held at an arbitrary position by locking the operation lever for holding position adjustment.

  In such a state, since both the memories 152 and 155 are not released from the column side bracket 132, the main user then unlocks the holding position adjusting operation lever to adjust the holding position of the steering wheel. When the main user desires the desired position of the steering wheel, the main user feels the moderation feeling when the engaging convex portion 152b1 of the memory 152 is engaged with and disengaged from the holding concave portion of the vehicle body side bracket. The engagement recess 155b1 of the second memory 155 can be recognized by a sense of moderation when engaging / disengaging from a part (holding portion) 133e of the bolt 133. For this reason, the main user can hold the steering wheel at a desired position by locking the holding position adjusting operation lever at a position where the sense of moderation is obtained.
