Japanese Patent No. 3613581

  In a tonneau cover device for a vehicle, it is desirable that the tonneau cover sheet covers the upper side of the rear luggage compartment in a substantially horizontal state so that the rear luggage compartment portion on the lower side of the tonneau cover sea is not seen from the outside as much as possible. The seat width in the left-right direction of the tonneau cover sheet can be set so that there is almost no gap between the tonneau cover sheet in a substantially horizontal state and the left and right rear inner portions of the vehicle body facing the rear luggage compartment. However, in a general vehicle, the vehicle width direction interval between the left and right rear inner portions of the vehicle body is narrower toward the upper side.

  Therefore, when the sheet width of the tonneau cover sheet including the sheet support member is set as described above, in the tonneau cover apparatus that guides the left and right ends of the sheet support member at least in the vertical direction by a pair of guide rails, In the existing technology, the seat support member is lifted along a pair of guide rails from the use position. When doing so, the left and right end portions of the seat support member bump against a pair of guide rails (or the left and right rear inner portions of the vehicle body) and become immovable, and the tonneau cover seat cannot be opened.

  Therefore, the seat width of the tonneau cover sheet including the seat support member is made smaller than the interval at the uppermost position in which the seat support member moves among the vehicle width direction intervals between the left and right rear inner portions of the vehicle body, and a pair of guides By arranging the rails in parallel in the vertical direction, the above problem can be solved and it is realistic, but the tonneau cover seat covers the upper side of the rear luggage compartment and the tonneau cover seat and the left and right rear inner parts of the vehicle body There is also a possibility that the gap between the guide rails becomes large, and the pair of guide rails protrudes greatly into the rear cargo compartment and becomes an obstacle.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a pair of guides for a seat support member in a vehicle in which the vehicle width direction interval between the left and right rear sides of the vehicle body facing the rear cargo compartment (the width in the vehicle width direction of the rear cargo compartment) becomes narrower toward the upper side. While being guided by the rail at a predetermined use position, the gap between the substantially horizontal tonneau cover seat and the left and right rear sides of the vehicle body is eliminated as much as possible, and the seat support member is moved from the use position along the pair of guide rails. It is an object of the present invention to provide a tonneau cover device for a vehicle that can be reliably raised and the tonneau cover sheet can be reliably opened.

  A tonneau cover device for a vehicle according to claim 1 includes a tonneau cover seat having a seat member that covers an upper side of a rear luggage compartment facing a rear opening of a vehicle body, and a seat support member attached to a rear end of the seat member, and a pair of left and right bodies of the vehicle body. A tonneau cover device provided with a pair of guide rails arranged along the rear pillar and guiding both left and right ends of the seat support member of the tonneau cover sheet, wherein the pair of guide rails is a vehicle between the guide rails. The rear end side portion of the tonneau cover sheet in a substantially horizontal state with the sheet supporting member being guided to a predetermined use position by a pair of guide rails so as to be widened toward the lower side in the width direction. The seat width in the left-right direction is substantially the same as the distance in the vehicle width direction between the pair of guide rails, and the seat support member extends along the pair of guide rails. And a seat width absorbing means for absorbing a difference in the seat width so as to reduce the seat width in accordance with a reduction in the vehicle width direction interval between the pair of guide rails when rising from the use position. To do.

  This tonneau cover device for a vehicle is applied to a vehicle in which the width in the vehicle width direction (the width in the vehicle width direction of the rear luggage compartment) between the rear side parts including the left and right rear pillars of the vehicle body facing the rear luggage compartment becomes narrower toward the upper side. It is. Since the pair of guide rails are provided in an inclined shape so that the vehicle width direction interval between the guide rails becomes wider toward the lower side, the pair of guide rails are arranged along the pair of left and right rear pillars. The tonneau cover sheet has a sheet member and a sheet support member attached to the rear end of the sheet member, and both left and right end portions of the sheet support member are guided by a pair of guide rails so that the position is variable at least in the vertical direction. .

  In the state where the seat support member is guided to the predetermined use position by the pair of guide rails, the lateral width of the rear end portion of the substantially horizontal tonneau cover seat is the distance in the vehicle width direction between the pair of guide rails. Therefore, the gap between the substantially horizontal tonneau cover sheet covering the upper side of the rear cargo compartment and the left and right rear inner sides of the vehicle body facing the rear cargo compartment can be eliminated as much as possible. When the seat supporting member is lifted from the use position along the pair of guide rails, the seat width is reduced by the seat width absorbing means as the distance in the vehicle width direction between the pair of guide rails is reduced. Since the difference in the sheet width is absorbed, the sheet support member is reliably raised along the pair of guide rails, and the tonneau cover sheet is reliably opened.

  In the invention of claim 1, the sheet width absorbing means has a bent portion provided at a central portion in the length direction of the sheet support member so that the sheet support member can be folded (invention 2). The means has at least one pair of bent portions provided symmetrically in the middle in the length direction of the sheet support member so that the sheet support member can be folded (Claim 3). When the support member rises from the use position along the pair of guide rails, the left / right length variable mechanism is configured to change the left / right length of the seat support member by contracting the seat support member in the vehicle width direction or bending it upward. (Claim 4), etc., can be adopted.

  According to a fourth aspect of the present invention, the seat support member includes a support member main body constituting a major portion of the sheet support member and a pair of left and right connecting support portions, and the left / right variable length mechanism includes at least both ends of the support member main body. And a telescopic mechanism having a guide hole that is fitted in a pair of coupling support portions so as to be stretchable in the left-right direction (Claim 5), and the rear end of the sheet member is a support member body of the sheet support member The seat width absorbing means is coupled to the pair of connection support portions and is not coupled to the pair of connection support portions. A pair of connecting support portions and a pair of non-coupled rear end side corner portions of the sheet member are configured to be bent (Claim 6), and the sheet width absorbing means is arranged along a pair of guide rails. A pair of sheet members The rear end corner portion having a pair auxiliary guide rails for guiding the (claim 7), it is possible to adopt a structure and the like.

  According to the tonneau cover device for a vehicle according to claim 1, a general vehicle has a vehicle width direction interval (a vehicle width direction width of the rear luggage compartment) between rear inner portions including left and right rear pillars of a vehicle body facing the rear cargo compartment. Although it becomes narrower toward the upper side, the tonneau cover seat in the substantially horizontal state and the rear inner side part of the vehicle body are applied to the vehicle in a state where the seat support member of the tonneau cover sheet is guided to a predetermined use position by a pair of guide rails. As a result, the rear luggage compartment portion on the lower side of the tonneau cover seat can be prevented from being seen from the outside as much as possible, and the seat support member is used along the pair of guide rails. The seat width absorbing means reduces the seat width in the left-right direction of the rear portion of the tonneau cover seat as the distance in the vehicle width direction between the pair of guide rails decreases. Therefore, the seat support member can be reliably lifted along the pair of guide rails from the use position, so that the tonneau cover sheet can be reliably opened, and the pair of guide rails can be connected between the guide rails. Can be arranged so as not to protrude greatly toward the rear cargo compartment along the pair of left and right rear pillars. A large space can be secured.

  According to the tonneau cover device of the second aspect, the sheet width absorbing means has the bent portion provided at the center in the length direction of the sheet support member so that the sheet support member can be folded, so that the sheet support member is in the use position. The tonneau cover sheet can be brought into a substantially horizontal state so that the sheet support member rises from the use position along the pair of guide rails. The bent portion at the center in the direction is folded upward to facilitate loading and unloading of luggage into the rear luggage compartment, reducing the left and right length of the seat support member, and reliably reducing the seat width of the rear portion of the tonneau cover sheet be able to.

  According to the tonneau cover apparatus of the third aspect, the sheet width absorbing means has at least one pair of bent portions provided symmetrically in the middle in the length direction of the sheet support member so that the sheet support member can be folded in a mountain. The tonneau cover sheet can be brought into a substantially horizontal state so that the seat support member is in an unbent state when the seat support member is in the use position, and the seat support member is lifted from the use position along the pair of guide rails. , At least one pair of left and right symmetrical bent portions in the middle of the length direction of the seat support member is folded upward to facilitate loading and unloading of luggage into the rear cargo room, and the left and right length of the seat support member is reduced. The sheet width of the rear portion of the tonneau cover sheet can be surely reduced.

  According to the tonneau cover apparatus of the fourth aspect, the seat width absorbing means contracts the seat support member in the vehicle width direction or bends upward when the seat support member rises from the use position along the pair of guide rails. Since the left and right length changing mechanism changes the left and right length of the seat support member, the seat support member is held in a horizontal state when the seat support member is lifted from the use position along the pair of guide rails. It is possible to reduce the seat width of the rear portion of the tonneau cover sheet by shrinking in the width direction or by bending the seat member upward so that the luggage can be easily put in and out of the rear luggage compartment, thereby reducing the lateral length. .

The guide support hole is formed so that the pair of connection support portions are telescopically fitted in the left-right direction. Therefore, the pair of connection support portions are guided by the pair of guide rails, and the pair of seat support members are paired. When the seat support member is lifted from the use position along the guide rail, the seat support member is reliably contracted in the vehicle width direction, and when the seat support member is lowered along the pair of guide rails, the seat support member is It can be reliably extended in the width direction.

  According to the tonneau cover device of the sixth aspect, the rear end of the sheet member is coupled to the support member main body of the sheet support member and is not coupled to the pair of connection support portions. Along with the reduction in the distance in the vehicle width direction between the pair of guide rails due to the rising of the member, the pair of connecting support portions and the uncoupled pair of rear end side corner portions of the seat member are configured to bend. Therefore, the lateral width of the seat member in the rear portion of the tonneau cover sheet can be increased, and the upper side of the rear luggage compartment can be reliably covered, and when the seat support member ascends along the pair of guide rails, The rear end corner portion can be bent to reliably reduce the sheet width of the rear portion of the tonneau cover sheet including the sheet member.

  According to the tonneau cover device of the seventh aspect, the sheet width absorbing means has a pair of auxiliary guide rails that are disposed along the pair of guide rails and guide the pair of rear end corner portions of the sheet member. Therefore, when the seat support member is lifted along the pair of guide rails, the pair of rear end corner portions can be guided by the pair of auxiliary guide rails and bend orderly.

  In the tonneau cover device for a vehicle according to the present invention, the pair of guide rails are provided in an inclined shape so that the distance in the vehicle width direction between the guide rails increases toward the lower side, and the seat support member of the tonneau cover sheet is a pair of guides. The lateral width of the rear end portion of the substantially horizontal tonneau cover seat is substantially the same as the distance in the vehicle width direction between the pair of guide rails while being guided to a predetermined use position by the rail. When the seat support member is lifted from the use position along the pair of guide rails, the seat width is reduced by the seat width absorbing means as the distance in the vehicle width direction between the pair of guide rails is reduced. The difference in sheet width is absorbed.

  As shown in FIGS. 1 and 2, a vehicle 2 such as an automobile equipped with the tonneau cover device 1 of the present invention has a rear opening 4 formed in the rear portion of a vehicle body 3 and a rear luggage compartment facing the rear opening 4. 5 is formed, and the upper end portion of the back door 6 is pivotally supported around the axial center in the vehicle width direction at the upper portion of the rear opening 4 of the vehicle body 3, and the rear opening 4 is opened and closed vertically by the back door 6. A seat back 7 is disposed on the front side of the rear cargo compartment 5, and the vehicle width direction interval between the rear inner sides including the left and right rear pillars 8 of the vehicle body 3 facing the rear cargo compartment 5 (the width of the rear cargo compartment 5 in the vehicle width direction). ) Is narrower toward the top.

As shown in FIGS. 1 to 4, the tonneau cover device 1 includes a tonneau cover sheet 10, a winding device 11, a pair of left and right guide rails 12, and a sheet width absorbing mechanism 13.

In this state, the pair of guide rails 12D, together with the pair of carriages 14, causes the sheet support member 21D to be positioned at a predetermined use position (a position indicated by a solid line in FIG. 9), and above and in front of the use position. It is guided linearly and movably over the open position (position indicated by a two-dot chain line in FIG. 9).

  When the seat support member 21D is guided to the use position by the pair of guide rails 12D, the seat width in the left-right direction of the rear end portion of the tonneau cover seat 10D in the substantially horizontal state is a vehicle between the pair of guide rails 12D. It is comprised so that it may become substantially the same as the space | interval of the width direction. Here, the rear end portion of the tonneau cover sheet 10D includes the rear end portions of the sheet support member 21D and the sheet member 20D, and the sheet width in the left-right direction of the sheet member 20D is uniform throughout the rear of the sheet member 20D. The sheet width is substantially the same as that of the end portion.

  When the seat support member 21D rises from the use position along the pair of guide rails 12D, the seat width absorbing mechanism 13D sets the seat width of the rear end side portion of the tonneau cover sheet 10D between the pair of guide rails 12D. The seat support member 21D absorbs a difference in seat width with respect to the vehicle width direction interval between the pair of guide rails 12D so as to be reduced as the vehicle width direction interval is reduced. The left and right length variable mechanism 13D is configured to shrink the seat support member 21D in the vehicle width direction to reduce the left and right length of the seat support member 21D when the seat support member 21D is lifted from the use position.

  The sheet support member 21D has a support member main body 27 and a pair of left and right connecting support portions 28 that constitute most of the seat support member 21D, and the left / right variable length mechanism 13D is formed at least at both ends of the support member main body 27. It has an expansion / contraction mechanism 13DA having a guide hole 27a for fitting the pair of connection support portions 28 so as to be extendable in the left-right direction.

  The rear end of the sheet member 20D is coupled to the support member main body 27 of the sheet support member 21D and is configured in a non-coupled state with the pair of connection support portions 28. The sheet width absorbing mechanism 13D is configured to raise the sheet support member 21D.

Since the left / right length changing mechanism 13D changes the left / right length of the sheet support member 21D, the sheet support member 21D is held in a horizontal state when the sheet support member 21D is lifted from the use position along the pair of guide rails 12D. Thus, the seat width of the rear portion of the tonneau cover sheet 10D can be reliably reduced by contracting in the vehicle width direction.

  The sheet support member 21D has a support member main body 27 and a pair of left and right connecting support portions 28 that constitute most of the seat support member 21D, and the left / right variable length mechanism 13D is formed at least at both ends of the support member main body 27. Since there is a guide hole 27a for fitting the pair of connection support portions 28 so as to be extendable in the left-right direction, the pair of connection support portions 28 are guided by the pair of guide rails 12D, so that the pair of seat support members 21D is a pair. When the seat support member 21D is lifted from the use position along the guide rail 12D, the seat support member 21D is reliably contracted in the vehicle width direction, and when the seat support member 21D is lowered along the pair of guide rails 12D, the seat The support member 21D can be reliably extended in the vehicle width direction.

  The rear end of the sheet member 20D is coupled to the support member main body 27 of the sheet support member 21D and configured to be uncoupled from the pair of connection support portions 28. The sheet width absorbing mechanism 13D is configured by raising the sheet support member 21D. Along with the reduction in the distance in the vehicle width direction between the pair of guide rails 12D, the pair of connecting support portions 28 and the pair of rear end side corner portions 20Da not coupled to the pair of seat members 20D are configured to bend. Therefore, when the lateral width of the seat member 20D in the rear portion of the tonneau cover sheet 10D can be increased to reliably cover the upper side of the rear luggage compartment 5, the seat support member 21D rises along the pair of guide rails 12D. The sheet width of the rear portion of the tonneau cover sheet 10D including the sheet member 20D can be reliably reduced by bending the pair of rear end side corner portions 20Da.

  The sheet width absorbing mechanism 13D includes a pair of auxiliary guide rails 14 that are disposed along the pair of guide rails 12D and guide the pair of rear end corner portions 20Da of the sheet member 20D. When 21D rises along the pair of guide rails 12D, the pair of auxiliary guide rails 14 can guide the pair of rear end corner portions 20Da and bend them in an orderly manner.

  In the tonneau cover device 1D, a biasing member such as a compression spring that biases the pair of connection support portions 28 toward the support member main body 27 toward the extension side may be provided. Further, the pair of auxiliary guide rails 14 may be fixedly provided on the rear pillar 8 instead of the guide rail 12D.
