Description

  The present invention relates to a tonneau cover device that covers an upper part of a cargo floor between a rear seat and a vehicle body rear door at substantially the same height as a seat back of the rear seat.

  2. Description of the Related Art Conventionally, as a tonneau cover device for a vehicle covering a tonneau portion, one described in Patent Document 1 is known.

  That is, a storage case in which the tonneau cover sheet is wound and stored so that it can be pulled out is provided inside, and the storage case extending in the vehicle width direction is supported by a pair of left and right guide rails on the left and right inner walls of the luggage compartment so as to be movable up and down. When the seat back is in the normal seated state, the storage case is positioned at the rear of the upper end of the seat back, while when the rear seat is moved forward on the seat cushion, it is guided by a plurality of guide rollers. The storage case is moved downward along a pair of left and right guide rails by traction means such as a belt, and the storage case is stored in a notch recess at the rear portion of the seat cushion.

  In short, what is disclosed in this Patent Document 1 is that the storage case in which the tonneau cover sheet is wound and stored includes a rear upper end portion of the seat back as a tonneau cover use position and a storage position of the rear portion of the seat cushion at the lower part of the cargo floor. It moves to 2 positions.

  However, in this conventional apparatus, since the storage case itself moves, there is a problem that the entire apparatus is large and complicated. In particular, the pair of left and right guide rails has sufficient rigidity to support the storage case itself. A structure with this is required.

  In order to solve such a problem, a roller part that winds and holds the tonneau cover is arranged at the lower part of the cargo compartment floor, while the rail inclined part along the seat back and the upper end part of the inclined part are continuously provided. A pair of left and right guide rails with a horizontal rail that extends rearward at approximately the same height as the seat back is provided on the left and right inner walls of the luggage compartment, and only the cloth-shaped tonneau cover is configured to move along the guide rails. It is possible to do.

  However, in this case, when the tonneau cover is pulled out to the rail horizontal portion, the tonneau cover is not properly extended along the rail inclined portion and the rail horizontal portion due to the cloth-like relationship. There was a problem that it was greatly bent downward between the horizontal portion and the roller portion.

In order to prevent the tonneau cover from being bent, if a guide rod extending in the vehicle width direction is stretched at the connecting portion between the rail inclined portion and the rail horizontal portion, the seat back is placed on the seat cushion when the tonneau cover is not used. When it is desired to use the luggage compartment in a forward-facing manner, the guide rod extends in the vehicle width direction, so there is a problem that expansion of the cargo compartment space and luggage compartment storage capacity are hindered, making it difficult to put it to practical use. .

  As shown in FIG. 5, two projecting shafts 46, 46 projecting outward in the vehicle width direction are provided at the left and right ends of the support bar 36, and the outer periphery of these projecting shafts 46, 46 is provided. In order to reduce the sliding resistance, the rollers 47 and 47 are rotatably fitted.

  As shown in FIGS. 5 and 6, rollers 47, 47 at both ends of the support bar 36 are disposed in the guide groove of the second guide rail 44 so as to move up and down along the second guide rail 44 of the support bar 36. It is composed.

  As shown in FIG. 5, a substantially semi-circular concave attachment / detachment groove 48 is formed along the vehicle width direction on the first guide rail 34 side of the support bar 36, and the attachment / detachment groove 48 serves as a tonneau cover engaging portion. The slider 50 is disposed.

  The slider 50 includes a base portion 51 detachably disposed in the above-described attachment / detachment groove 48 and a slide bar 52 formed integrally or integrally with the base portion 51, as shown in FIGS. The left and right ends of the slide bar 52 are disposed in the guide groove of the first guide rail 34.

  The front end portion of the above-described tonneau cover 30 is engaged with the slide bar 52 in the entire width in the vehicle width direction, and the front end portion of the drive cable 43 is located at both end portions of the slide bar 52 in the groove of the first guide rail 34. It is connected to.

  As a result, the slider 50 can engage with the tonneau cover 30 and move the support bar 36 along the second guide rail 44 as the tonneau cover 30 moves.

  The above-described tonneau cover 30 moves upward from the winding storage position at the lower part of the cargo compartment floor 19 shown in FIG. 3 to the upper end of the inclination in the inclination direction along the seat back 8 as shown in FIGS. It is necessary to horizontally move rearward from the inclined upper end through the state and the states of FIGS. 11 and 12 at substantially the same height as the upper end of the seat back 8 as shown in FIG.

  Therefore, as shown in FIGS. 9, 10, and 12, the above-described second guide rail 44 includes a rotation permission portion 53 that allows rotation around the axis of the support bar 36 at the upper end portion thereof.

  As shown in FIG. 13, the rotation allowing portion 53 includes two arc portions 53 a and 53 b that are curved corresponding to the radius of the length connecting the center C of the support bar 36 and the outer periphery of the roller 47, and the radius of the roller 47. 3 curvature portions 53c, 53d, 53e corresponding to the curvature, two regulating portions 53f, 53g at the time of tonneau cover extension for regulating the rotation of the support bar 36 over a predetermined angle, and a support bar 36 over a predetermined angle The two restricting portions 53h and 53i at the time of retracting the tonneau cover for restricting the reverse rotation are integrally formed in the order of the respective elements 53a, 53c, 53f, 53i, 53d, 53b, 53e, 53g, and 53h. The above-described rounded portion 53e and the restricting portion 53g that are formed in a shape and serve as a support portion of the support bar 36 that is stationary at the corresponding position of the connecting portion 34C. It is configured to so that.

  Further, the internal space of the rotation allowance portion 53 is continuous with the guide groove of the second guide rail 44, and the support bar 36 moves up and down via the slider 50 by the drive of the drive cable 43, and the two rollers at both ends thereof When 47 and 47 are located in the internal space of the rotation allowing portion 53 from the guide groove of the second guide rail 44 and the upper roller 47 contacts the rounded portion 53d as shown in FIG. The above increase is regulated.

  When the slider 50 moves from the state shown in FIG. 9 in the direction of extending the tonneau cover 30 (the direction shown in the drawing), the two rollers 47 and 47 move along the two arc portions 53a and 53b as shown in FIG. When the positions of the two rollers 47 and 47 are restricted by the corresponding two restricting portions 53f and 53g as shown in FIG. 12, the further rotation of the support bar 36 is restricted, and the support bar 36 has the first guide. The rail 34 stops at a position corresponding to the connecting portion 34C.

  Therefore, when the slider 50 further moves in the extending direction of the tonneau cover 30, the slider 50 is detached from the attaching / detaching groove 48 of the support bar 36, and only the slider 50 is along the rail horizontal portion 34B of the first guide rail 34. As shown in FIG. 4, the tonneau cover 30 can completely cover the upper part of the cargo compartment floor 19 as shown in FIG. 4, and when the tonneau cover 30 is extended, the support bar 36 is provided in the middle portion of the tonneau cover 30, that is, the connecting portion. The tonneau cover 30 can be held from the lower part at a portion corresponding to 34C.

  In short, the support bar 36 is rotated from the position shown in FIG. 9 to the position shown in FIG. It is configured to move between the horizontal portion 34B.

  When the tonneau cover 30 in the extended state shown in FIG. 4 is stored, the front of the vehicle along the rail horizontal portion 34B of the first guide rail 34 is driven by driving the drive cable 43 in the storage direction (arrow y direction in FIG. 7). Since the slider 50 moving to the position fits into the attachment / detachment groove 48 in the support bar 36 at the stop position (see FIG. 12), when the slider 50 moves in the retracting direction of the tonneau cover 30 from this fitted state, After the two rollers 47 and 47 move along the arc portions 53a and 53b as shown in FIG. 10, the two rollers 47 and 47 are moved by the two restricting portions 53h and 53i during the reverse rotation as shown in FIG. The support bar 36 is rotated until the position is regulated.

  Since the two rollers 47, 47 shown in FIG. 9 are located on the extension line of the guide groove of the second guide rail 44, the slider 50 moves with the support cover 36 when the slider 50 further moves in the retracting direction of the drain cover 30. Move down. The slide bar 52 of the slider 50 is guided downward by the rail inclined portion 34A of the first guide rail 34, and the two rollers 47, 47 and the support bar 36 are moved downward by the second guide rail 44 parallel to the rail inclined portion 34A. After being guided, the tonneau cover 30 is wound around the roller portion 31 and stored in a concealing position below the cargo compartment floor 19 shown in FIG.

  In the figure, arrow F indicates the front of the vehicle, and arrow R indicates the rear of the vehicle.

  In the tonneau cover apparatus configured as described above, when the cloth-shaped tonneau cover 30 is extended to cover the upper part of the cargo compartment floor 19, the reversible motor 40 is driven in the tonneau cover extending direction from the state of FIG. When the slider 50 is pulled and driven in the tonneau cover extending direction by the driving force of the drive cable 43 driven in the direction of the arrow x, the slider 50 fitted to the support bar 36 and the slider 50 and the support up to the inclined upper end position of the seat back 8 are supported. The bar 36 rises in conjunction with the state shown in FIG.

  In the raised position of the support bar 36 shown in FIG. 8, the support bar 36 is allowed to rotate by the rotation allowing portion 53. Therefore, when the slider 50 is further driven in the extending direction, the support bar 36 is supported after rotating a predetermined amount. 11 (see the rounded portion 53e and the restricting portion 53g), the slider 50 moves away from the support bar 36 while pulling the tonneau cover 30 and moves to the position shown in FIG. The upper part of the cargo floor 19 is completely covered.

In this case, since the support bar 36 extends in the vehicle width direction at the connection portion 34C corresponding to the upper end portion of the seat back 8, the tonneau cover 30 does not bend.
On the contrary, when the tonneau cover 30 shown in FIG. 4 is stored to expand the cargo space and improve the luggage storage property, the reversible motor 40 is driven in the tonneau cover storing direction from the state of FIG. When the slider 50 is pressed and driven in the tonneau cover retracting direction by the driving force of the drive cable 43 driven in the arrow y direction, the slider 50 moves forward of the vehicle independently of the support bar 36 in the rail horizontal portion 34B. When the slider 50 reaches the connecting portion 34C of the first guide rail 34, the slider 50 is fitted to the support bar 36. Therefore, the slider 50 and the support bar 36 interlock with each other in the region below the connecting portion 34C. As shown in FIG. 3, the tonneau cover 30 can be wound and stored on the roller portion 31 at the concealment position below the cargo floor 19.

  In this case, when the seat back 8 of the rear seat 10 is moved forward on the seat cushion 7 as shown by phantom lines in FIGS. 1 and 2, the luggage space can be further expanded and the luggage storage property is further improved. be able to.

  As described above, the tonneau cover device of the above-described embodiment includes the vehicle body rear door (see the rear hatch 2), the rear seat 10 having the seat back 8 that can be tilted forward, and the rear seat 10 and the vehicle body rear door (rear hatch 2). A tonneau cover device that covers the luggage compartment floor 19 at substantially the same height as the upper end of the seat back 8, and includes a cloth-like tonneau cover 30, The upper end of the seat back 8 is moved upward from the concealing position of the lower part of the cargo compartment floor 19 to the upper end (refer to the connecting portion 34C) in the vertical direction along the seat back 8 from the upper end (inclined upper end). And an extension mechanism (see support bar 36) that horizontally moves rearward at substantially the same height as above and holds the midway part of the tonneau cover 30 at the upper end (see connection part 34C). Than is.

  According to this configuration, when the cloth-like tonneau cover 30 is used, the tonneau cover 30 is inclined from the concealment position (see FIGS. 2, 3, and 5) below the cargo compartment floor 19 along the seat back 8 (vertical direction). ) To the upper end of the slope (see the connecting portion 34C) (see FIG. 8), and moves horizontally from the upper end of the slope to the rear at substantially the same height as the upper portion of the seat back 8, Since the midway part of the tonneau cover 30 is held by the above-mentioned upper end part (see the connection part 34C) by the extension mechanism (see the support bar 36), the tonneau cover 30 is not bent in the tilt direction (vertical direction) and the horizontal direction. It can be extended to cover the upper part of the cargo floor 19.

  In addition, when the tonneau cover 30 is not used, the tonneau cover 30 can be stored in the concealed position below the cargo compartment floor 19, so that the cargo compartment space can be expanded and the luggage storage performance can be improved.

In addition, since the cloth-like tonneau cover 30 is used, the apparatus can be made compact.
Further, the extension mechanism (see the support bar 36) extends in the vehicle width direction and is configured to move up and down in conjunction with only the vertical movement of the tonneau cover 30 along the seat back 8.

  According to this configuration, since the extension mechanism (see the support bar 36) extends in the vehicle width direction, the tonneau cover 30 can be extended by the extension mechanism (support bar 36) without being bent over substantially the entire width in the vehicle width direction. In addition, since the extension mechanism (support bar 36) moves up and down in conjunction with only the movement of the tonneau cover 30 along the seat back 8 in the inclined direction, the extension mechanism is interlocked with the tonneau cover 30 when the tonneau cover 30 is not used. The (support bar 36) moves to the concealment position below the cargo compartment floor 19.
